One Psychedelic Trip Can Make You See Consciousness Everywhere

The Day the World Woke Up

I remember exactly where I was when I first learned that some people, after a single psychedelic trip, start seeing consciousness in everything. Not metaphorically. Not poetically. They literally start believing that rocks, rivers, and radiators might have some form of inner experience.

It sounded like a punchline to a stoner joke. But the data from Nayak and Griffiths (2022) tells a different story. They surveyed 1,606 people who reported having a belief-changing psychedelic experience. What they found was not subtle. Before the experience, 26% of participants said plants had consciousness. After the experience, 61% did. That is not a small shift. That is a landslide.

The authors were careful. They did not ask people if they thought plants might be conscious in some vague philosophical sense. They asked for direct attributions of consciousness to specific categories of living and non-living things. And the changes did not fade with time. People who had taken psychedelics years ago still reported the same elevated attributions of consciousness today (Nayak & Griffiths, 2022).

This is not about hippie mysticism. This is about a measurable, persistent change in how people perceive the fundamental nature of reality.

What Exactly Happens to Your Mind

The study was simple in design but profound in its implications. Nayak and Griffiths recruited participants online through social media, newsletters, and word of mouth. The only requirement was that you had a psychedelic experience that changed a core belief about yourself, the world, or existence. Most people reported using psilocybin mushrooms (magic mushrooms) or LSD.

Participants rated their attributions of consciousness to 13 categories of entities on a scale from 0 (no consciousness) to 100 (full human-like consciousness). They did this twice: once recalling how they felt before the experience, and once describing how they felt after. The researchers also measured mystical experience intensity, belief in free will, and superstitious beliefs.

The results were not evenly distributed across all entities. Some categories saw enormous jumps. Others saw smaller but still significant shifts.

The Big Winners

• ▸Non-human primates: from 63% to 83% attribution of consciousness
• ▸Quadrupeds (dogs, cats, horses): from 59% to 79%
• ▸Insects: from 33% to 57%
• ▸Fungi: from 21% to 56%
• ▸Plants: from 26% to 61%

Notice something? The increases were larger for entities that are already somewhat ambiguous. Most people already think monkeys and dogs have some consciousness. The psychedelic experience pushed those numbers higher. But the really dramatic shifts were for insects, fungi, and plants. These are entities that many people, before a psychedelic experience, consider to be essentially unconscious automatons.

After the experience, more than half of participants attributed significant consciousness to plants and fungi. That is not a fringe view anymore. That is a majority position within this population.

The Surprising Ones

Then came the really unexpected findings.

• ▸Inanimate natural objects (rocks, rivers, mountains): from 8% to 26%
• ▸Inanimate manmade objects (chairs, computers, cars): from 3% to 15%

These numbers are lower, but the relative increase is massive. The attribution of consciousness to rocks tripled. For manmade objects, it increased fivefold. A small but significant minority of people, after one psychedelic trip, started seeing consciousness in a chair.

Nayak and Griffiths (2022) report that these changes did not decrease over time. People who had their experience 10 or 20 years ago still reported the same elevated attributions of consciousness today. This is not a temporary high. It is a permanent shift in worldview.

The Mystical Experience Connection

Not every psychedelic trip produces these effects. The key variable was something the researchers called "mystical experience." They used a validated questionnaire that measures feelings of unity, sacredness, ineffability, and transcendence of time and space. People who scored higher on mystical experience showed larger increases in consciousness attribution.

This makes sense. A mystical experience is not just seeing colors or feeling euphoria. It is a profound sense of connection to everything. The boundary between self and world dissolves. If you have ever felt like you were part of a larger whole, you can imagine how that might change how you see a tree or a rock.

But here is the twist. The researchers also measured belief in free will and superstitious beliefs. Neither changed significantly after the psychedelic experience (Nayak & Griffiths, 2022). This is important. It tells us that the effect is specific to consciousness attribution, not a general loosening of rationality or a regression to magical thinking. People did not become more superstitious. They did not suddenly believe in ghosts or fate. They just started seeing consciousness in more places.

Why This Should Surprise You

If you have never taken a psychedelic, this might sound like a bunch of people getting confused and then staying confused. But the data suggests something more interesting. The changes were not random. They followed a pattern.

The largest increases were for entities that are biologically alive but not obviously sentient: insects, fungi, plants. The smallest increases were for obviously inanimate objects. People did not start thinking their toaster was having a conversation with them. They started thinking that a tree might have some form of awareness.

This pattern mirrors something called the "continuity hypothesis" in philosophy of mind. The idea is that consciousness might exist on a spectrum, with humans at one end and rocks at the other, and everything in between having some degree of inner experience. Most people reject this idea intuitively. After a psychedelic experience, many people embrace it.

Nayak and Griffiths (2022) point out that this is consistent with the "entropic brain" theory of psychedelic action. Under psychedelics, the brain's normal hierarchical organization breaks down. New connections form between previously separate networks. The rigid categories that normally separate self from world, human from animal, living from non-living, become permeable.

What This Research Does Not Prove

Let me be clear about what this study does not show.

It does not show that rocks actually have consciousness. The study measured beliefs, not reality. People might be wrong. They might be projecting their own inner experience onto the world. That is a real possibility.

It does not show that psychedelics cause this effect in everyone. The participants were self-selected. They already reported a belief-changing experience. People who had a bad trip or no lasting change would not have responded to the survey. The effect size might be smaller in the general population.

It does not show that the effect is permanent for everyone. The data shows that for people who completed the survey years later, the effect persisted. But we do not know about people who might have changed their minds again later.

The authors themselves note that this was a retrospective study. People were recalling how they felt before the experience. Memory is imperfect. There could be a bias toward seeing the experience as more transformative than it actually was.

But here is the thing. The effect was large. The sample was large. The pattern was consistent across different entities. And it survived statistical controls for age, gender, education, and religious background. This is not a fluke.

What This Actually Means

This research changes how we think about psychedelics, consciousness, and the nature of belief itself. Here is what it means in practical terms.

• ▸Psychedelics can permanently change your ontology. Not just your mood or your personality. Your fundamental assumptions about what exists and what has inner experience. This is a deeper level of change than most therapies aim for.

• ▸The effect is specific to consciousness attribution, not general irrationality. People do not become more superstitious or lose their belief in free will. They become more animistic in a targeted way. This suggests the brain has a dedicated mechanism for attributing consciousness, and psychedelics recalibrate it.

• ▸Mystical experience is the key, not the drug itself. The same dose of psilocybin can produce wildly different outcomes depending on set and setting. The mystical quality of the experience, not the chemical, predicts the change. This means we might be able to induce similar shifts through meditation, breathwork, or other non-pharmacological methods.

• ▸The change is durable. If you shift your attribution of consciousness after a psychedelic experience, you are likely to stay shifted. This has implications for how we think about belief change in general. Some beliefs are sticky. This one is extra sticky.

• ▸This challenges the default scientific view of consciousness. Most neuroscientists assume consciousness is an emergent property of complex nervous systems. But if people consistently start seeing consciousness in plants and fungi after a psychedelic experience, maybe our default view is incomplete. Maybe consciousness is more widespread than we assume. Or maybe the brain is wired to see it everywhere under certain conditions. Either way, the default view needs an explanation for why this happens.

The most honest takeaway is this. We do not know if plants are conscious. We do not know if rocks have any inner experience. But we now know that a single psychedelic experience can make a significant portion of the population believe they are. That is a fact about human psychology that demands an explanation.

And if you are the kind of person who has never considered that a tree might be aware of you, this research might make you wonder. Not because the data proves it. But because the data proves that something about the human mind, under the right conditions, can see the world that way. And that something might be telling us more about reality than we want to admit.
