The powerful psychedelic N,N-dimethyltryptamine (DMT) induces some of the most profound and intense visual experiences known to human consciousness. When DMT enters the brain, it significantly alters how the visual cortex processes information, leading to extraordinary perceptual changes.
DMT dramatically affects the brain’s primary visual cortex, causing neurons to respond to larger areas of the visual field than normal. This neurological change results in distinctive visual phenomena like peripheral blurring and tunnel vision, where central vision remains sharp while the edges become distorted.
Neural Mechanisms
The drug creates a unique pattern of cortical activation similar to actual visual stimulation, even when users have their eyes closed. This explains why many people report “seeing with eyes shut” during a DMT experience.
The visual phenomena experienced during DMT journeys exhibit remarkable consistency across diverse user populations, creating what many describe as a distinct “DMT World.” Users frequently report encountering intricate geometric patterns that manifest as complex mathematical structures, often described as sacred geometry or fractal patterns that seem to extend infinitely. These patterns typically pulse with vibrant, otherworldly colors that transcend ordinary visual perception, creating synesthetic experiences where colors appear to have sound or emotional qualities.
Entity encounters represent another significant aspect of DMT visuals, with users consistently reporting interactions with seemingly autonomous beings. These entities often appear as benevolent female presences radiating maternal energy, playful jesters or clowns that appear to test or teach the experiencer, the famous “machine elves” first described by Terence McKenna, or beings with reptilian or insectoid characteristics. These encounters frequently feel more real than ordinary reality to many users, leading to profound questions about consciousness and reality itself.
DMT produces consistent visual themes across different users, creating a recognizable “DMT World” with specific characteristics:
Geometric Patterns
Users typically experience:
The environmental context of DMT visuals typically manifests as extraordinarily complex and multidimensional spaces that defy conventional geometric understanding. Users frequently describe entering what appears to be higher-dimensional spaces that cannot be adequately described using normal spatial terminology. These spaces often include what are commonly termed “waiting rooms” – transitional areas that seem to serve as gateways to deeper aspects of the experience.
Tunnel-like structures frequently appear as connecting pathways between different visual realms, often accompanied by a sensation of rapid movement or acceleration. The visual landscapes encountered extend far beyond ordinary perception, often incorporating impossible architectures and spaces that seem to fold in on themselves in ways that challenge our understanding of spatial relationships.
The “DMT World” often contains distinctive structural features:

Scientific research has revealed fascinating insights into how DMT affects neural processing, particularly in relation to visual perception. The substance creates a unique neurological state characterized by a distinctive balance between top-down and bottom-up information processing in the brain. Studies have shown significant alterations in normal alpha-band rhythms typically present during closed-eye states, while simultaneously increasing forward wave activity. This neurological restructuring appears to temporarily reorganize the brain’s normal hierarchical processing patterns, potentially explaining the profound alterations in consciousness and perception that characterize the DMT experience.
The safe navigation of DMT experiences requires careful attention to multiple factors that can significantly impact both the quality and safety of the experience. Physical setting plays a crucial role – environments should be carefully chosen to minimize external disturbances and maximize comfort and security.
The presence of an experienced, sober guide or sitter is essential, as they can provide both practical and emotional support during the intense and potentially disorienting experience. Medical considerations are equally important, with particular attention needed for individuals with cardiovascular conditions or those taking certain medications, especially antidepressants which can interact dangerously with DMT. Mental health history should also be carefully evaluated, as the intense nature of DMT experiences can potentially exacerbate underlying psychological conditions.
Physical Setting
A safe DMT experience requires careful preparation:
Medical Precautions
DMT should be avoided by people:
The temporal characteristics of DMT experiences vary significantly depending on the method of administration and individual factors. When smoked or vaporized, DMT produces an incredibly rapid onset of effects, typically reaching peak intensity within seconds to minutes. These experiences usually last between 30-45 minutes, with the most intense visual phenomena occurring during the first 10-15 minutes.
Oral consumption, particularly in traditional ayahuasca preparations, produces a markedly different timeline, with effects lasting up to 4-6 hours and showing a more gradual onset and descent. The intensity curve typically shows a sharp peak within the first few minutes when smoked, while oral consumption creates a more undulating pattern of intensity over several hours.
The visual effects of DMT typically last:
The generation of DMT visuals involves complex neurological mechanisms that fundamentally alter how the brain processes visual information. When DMT molecules bind to serotonin receptors, particularly the 5-HT2A receptors abundant in the visual cortex, they trigger a cascade of neural events that dramatically modify normal visual processing. This interaction leads to increased neural plasticity and altered communication patterns between different brain regions. The visual cortex begins processing information in novel ways, creating patterns and imagery that don’t correspond to external stimuli. Additionally, DMT affects the default mode network (DMN), a brain system involved in self-reflection and consciousness, leading to profound alterations in how visual information is integrated with other aspects of consciousness. This complex interplay of neural systems results in the characteristic geometric patterns, entity encounters, and other visual phenomena associated with DMT experiences.
The safety profile of DMT visuals requires a nuanced understanding of both physiological and psychological factors. While the visual experiences themselves don’t directly cause physical harm, the intensity and reality-shattering nature of these visions can be psychologically challenging. The main risks arise from inappropriate settings, underlying health conditions, or psychological vulnerabilities. The profound disorientation that can accompany DMT visuals necessitates careful preparation and environmental control. Users may experience temporary increases in heart rate and blood pressure, which can be concerning for individuals with cardiovascular conditions. The psychological impact can be significant, potentially triggering latent mental health issues or causing temporary dissociative states. However, when approached with proper preparation, guidance, and integration support, most individuals can navigate these experiences safely. The presence of a knowledgeable sitter is crucial, as they can provide grounding and support during moments of intense visual phenomena or psychological challenge.
DMT produces a unique visual landscape that distinguishes it from other psychedelic substances in several key ways. Unlike the gradually building and wavelike visual patterns common with substances like LSD or psilocybin, DMT creates an immediate and overwhelming immersion into a completely foreign visual realm. The geometric patterns are typically more complex and multidimensional, often described as impossible to fully comprehend with our normal spatial understanding.
Entity encounters are far more common and consistent with DMT than with other psychedelics, often involving interactive experiences with seemingly autonomous beings. The visual space itself often appears to operate under different physical laws, with users reporting experiences of higher dimensions and non-Euclidean geometry. The intensity and clarity of these visuals typically surpass those of other psychedelics, with users reporting crystal-clear visions even with eyes closed. The rapid onset and short duration also create a more concentrated and intense visual experience compared to the more gradual unfolding typical of other psychedelics.
The potential for lasting effects from DMT visuals extends beyond the immediate experience and can manifest in various ways. While the acute visual phenomena are temporary, the impact on perception and consciousness can persist long after the experience. Some users report enhanced pattern recognition, increased sensitivity to visual stimuli, or occasional flashbacks in the days or weeks following use. More significantly, the profound nature of DMT visuals often leads to lasting psychological and philosophical changes.
Users frequently report shifted perspectives on reality, consciousness, and existence itself. These changes can be both positive and challenging – while many report increased creativity, spiritual awareness, and psychological insight, others may struggle to integrate particularly intense or challenging visual experiences into their everyday reality. The integration process is crucial, as unprocessed experiences can lead to psychological distress or confusion. Professional integration support may be beneficial for those struggling to contextualize their visual experiences within their normal worldview.

We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience, regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level. These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML, adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements, alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website. In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels; descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups), and others. Additionally, the background process scans all the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology. To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers).
Despite our very best efforts to allow anybody to adjust the website to their needs. There may still be pages or sections that are not fully accessible, are in the process of becoming accessible, or are lacking an adequate technological solution to make them accessible. Still, we are continually improving our accessibility, adding, updating and improving its options and features, and developing and adopting new technologies. All this is meant to reach the optimal level of accessibility, following technological advancements. For any assistance, please reach out to
