Of all the things people say about DMT, the most puzzling may be this: it felt more real than real. Not like a dream, not like a film, but realer than the room they woke up in. It is the reason many people take their experiences seriously for years afterwards, and the reason this question sits at the centre of our DMT section. This article sets out what researchers have measured about that feeling, what brain science says about how we tell real from imagined, and what has never been tested.

How real do people say DMT feels?

Very real, when asked. In a 2020 Johns Hopkins online survey, 2,561 self-selected people described their single most memorable DMT entity encounter (see our overview of DMT entity encounters). Most said the entity existed in some real but different dimension of reality (Davis et al., 2020). According to a later field study that compared its results with the survey, 81% reported the encounter as “hyperreal”, more real than everyday reality (Michael et al., 2021). On a 0–100 scale, respondents rated the realness of the encounter 77.3 for the moment itself but 63.2 when thinking about it at the time of the survey (Davis et al., 2020). So remembered realness fades, though it stays high. Evidence: preliminary (self-selected, retrospective survey).

Unprompted, the picture changes. A team led by David Lawrence of the University of Toronto coded 3,778 DMT experiences posted to an online forum. Only 22 reports (0.6%) said the experience felt more real than everyday reality (Lawrence et al., 2022). That does not mean only 0.6% felt it; people describing a trip in their own words may simply not mention it. It means the number depends heavily on whether someone asks. Evidence: preliminary.

Careful lab interviews add nuance. In a 2026 study, 23 people were interviewed in fine detail after DMT given during brain scanning. A “feeling of reality” came up in 26% of interviews: some described the experience or its contents as real (22%), but others described parts as unreal (9%), seeming imagined or virtual. One participant said that, although they guessed it was an illusion, it felt very tangible (Sanders et al., 2026). Realness, in other words, is not all-or-nothing, and DMT can make things feel less real as well as more. Evidence: preliminary.

Is the “more real than real” feeling unique to DMT?

No. In a 2019 survey of “God encounter” experiences, people whose encounter happened without any drug rated it 72.7 out of 100 for being more real than everyday consciousness. People describing a DMT encounter rated theirs 77.5, close behind (Griffiths et al., 2019). Both groups were self-selected. Evidence: preliminary.

Near-death experiences show something similar in memory. In a small study, eight coma survivors with near-death experiences rated those memories using a standard questionnaire for memory characteristics. Their near-death memories carried more of the features typical of real-event memories than their memories of actual real events did, and more than imagined ones (Thonnard et al., 2013). A memory can feel vividly real because of its emotional weight and intensity, which is a reason to treat vividness as a sign of intensity, not accuracy. Evidence: preliminary (eight people). For how DMT and near-death experiences compare, see does the brain release DMT when you die.

What do people mean by “real”?

The word does a lot of work. When people say DMT felt more real, they may mean at least five different things, and the science below mostly concerns the first. This list is our own framing for clarity, not a published scale:

1. Perceptual realness: the sense that something is out there, not imagined.
2. Presence: the felt solidity and aliveness of the world and of oneself.
3. Conviction: the belief that the other world is the true one.
4. The noetic feeling: the sense of having learned something true.
5. Familiarity: the feeling of having always known the place or the beings.

How does the brain decide what is real?

Neuroscientists call this reality monitoring: telling apart signals that come from the world from those the mind makes up. In 2023, Nadine Dijkstra and Stephen Fleming had people imagine a faint pattern while watching visual noise, then, on a single surprise trial, showed some of them a real faint pattern. When the real pattern matched what they were imagining, 41% judged it real; when it did not match, 25% did (272 participants) (Dijkstra and Fleming, 2023). Evidence: established in this paradigm, using simple visual patterns.

The authors’ conclusion: imagined and perceived signals mix together, and the brain calls something real when the combined signal crosses a threshold. When imagined signals are strong enough, they can become indistinguishable from reality (Dijkstra and Fleming, 2023). Evidence: preliminary as a general account of how the brain judges reality.

A 2025 brain-scanning study took this further. Judgments of reality tracked the combined strength of activity in the fusiform gyrus, a mid-level visual area, whether that activity came from imagining or seeing. Its moment-to-moment fluctuations predicted confusions between imagery and perception, and it interacted with a frontal network that encoded the yes-or-no judgment “real” (Dijkstra et al., 2025). Ordinary reality monitoring works well most of the time; these are subtle effects in careful experiments. Evidence: preliminary.

A different idea concerns presence, the second meaning above. Anil Seth and colleagues proposed in 2011 that the felt reality of the world and the self depends on the brain successfully predicting signals from inside the body, with the anterior insula acting as a comparator, and they linked failures of this process to depersonalisation (Seth et al., 2011). It is a theoretical model and has not been tested in psychedelic states. Evidence: unresolved.

Has reality monitoring been tested under DMT?

No. A 2024 psilocybin brain-imaging study of visual imagery suggested that reality monitoring may depend on top-down connections to early visual areas and that higher doses would give more reason to examine it, but its own participants received only a low to moderate dose (Stoliker et al., 2024). We re-ran a literature search in Europe PMC on 20 October 2026, combining reality-monitoring and reality-testing terms with DMT, psilocybin, LSD, ayahuasca and psychedelics. It returned 159 records: reviews, theory papers, clinical reports and the 2024 imaging study, but no experiment that measured reality monitoring while someone was under a psychedelic (Europe PMC search). Evidence: established that it has not been done, as far as indexed literature shows.

That gap matters. If DMT raises the brain’s internal signal strength, or lowers the threshold for calling it real, the Dijkstra framework would predict exactly the kind of “realer than real” verdict people report. That is our own hypothesis, built by joining two separate literatures, not a finding. It could be tested with the same tasks used in the lab. Evidence: unresolved.

The noetic quality: why it feels like knowledge

In 1902 the psychologist William James listed a “noetic quality” as one of two defining marks of mystical states: they seem to those who have them to be “states of knowledge”, and they tend to carry “a curious sense of authority for after-time” (James, 1902). Modern DMT reports echo that. In the 3,778 coded forum reports, 19.0% included the gain of insightful knowledge experienced at an intuitive level, and 8.9% expressed certainty of having encountered ultimate reality (Lawrence et al., 2022). Evidence: preliminary (reports).

A related feeling is familiarity: the sense of having been there before, or of knowing the beings. It appeared in 12.8% of the forum reports (Lawrence et al., 2022). In a 2026 online survey of 1,050 people, psychedelic experiences were rated higher on every familiarity item than autobiographical memories or déjà vu (Lawrence, Doss and O’Connor, 2026). A 2024 re-analysis of 10 memory datasets found that psychedelics given while memories form tend to impair detailed recollection while enhancing familiarity (Doss et al., 2024). Most of those datasets did not involve DMT. Evidence: preliminary.

Can the feeling of truth be wrong?

Yes, and lab work shows how. In a preregistered experiment with 300 people, statements shown just after solving an anagram were rated as more true, even when they were false, and especially when people reported an “Aha!” moment (Laukkonen et al., 2020). In a follow-up, priming people towards wrong answers produced false insights on 37% of the relevant anagram trials in one experiment; they felt weaker than correct insights but were common (Grimmer et al., 2022). The authors note that, normally, feelings of insight usually accompany correct ideas. Evidence: established in these lab tasks, with simple materials.

Psychedelics reliably increase the feeling of insight. A 2025 systematic review of 98 studies found insight was higher on a psychedelic than on placebo in 43 of the 46 studies that compared them, and was linked to clinical improvement in 25 of 29 studies that looked (Kugel et al., 2025). Whether the insights were accurate was not among the outcomes the review reports. A 2024 theory paper proposes that psychedelics increase both the number and the felt intensity of insights, false ones included (McGovern et al., 2024). Evidence: preliminary for the theory; the accuracy of psychedelic insights is unresolved.

When the real world stops feeling real

The sense of reality can also go down. In depersonalisation-derealisation disorder, people perceive the world correctly but feel it, or themselves, as unreal for months. A 2023 systematic review of 23 studies puts its prevalence at around 1% of the general population (Yang et al., 2023). In an internet survey of 394 adults with the condition, about half said a drug first set it off; cannabis and hallucinogens were the most common triggers. There were no DMT-specific data, and people may have been vulnerable beforehand (Simeon et al., 2009). Evidence: preliminary. It is tempting to see realness as one dial that DMT turns up and depersonalisation turns down; that is our framing, not a tested model.

What the feeling does and does not show

The evidence supports a modest conclusion. The feeling that something is real, true or familiar is produced by the brain and can be strong without the contents being accurate; that is shown in ordinary lab tasks, in near-death memories and in drug-free spiritual experiences. It does not follow that DMT experiences are “just” hallucinations: the feeling of realness cannot prove them real, and it cannot prove them unreal either. That question is for other kinds of evidence. Evidence: preliminary.

• Whether DMT changes the brain’s reality threshold or signal strength: never measured (unresolved).
• Whether in-the-moment realness differs from remembered realness for the same person: only one survey has compared ratings, and retrospectively (unresolved).
• Whether people who rate an experience as more real later change their beliefs more (unresolved).
• Whether the insights people bring back are accurate: almost never assessed (unresolved).
