Many people expect a psychedelic experience to bring feelings of connection, awe, or emotional healing. Others prepare for difficult moments involving fear or anxiety. Few people expect shame.
Yet our newest peer-reviewed study suggests they probably should.
Researchers from Unlimited Sciences, Johns Hopkins University, Baylor College of Medicine, NYU, Mount Sinai, and other collaborating institutions examined the experiences of 679 adults who planned to use psilocybin in real-world settings. Participants completed surveys before their experience, within days afterward, several weeks later, and again months later, allowing researchers to follow how emotions changed over time rather than relying on memories years after the fact.
One finding stood out immediately.
Nearly 68% of participants reported experiencing shame, guilt, or both during their psilocybin experience.
That number challenges a common assumption about psychedelic experiences. Difficult emotions are often discussed in terms of fear, confusion, or anxiety, but shame has received remarkably little scientific attention.
Why study shame?
Psychologists distinguish shame from guilt, even though people often use the words interchangeably.
Guilt generally focuses on behavior.
"I did something wrong."
Shame tends to focus on identity.
"There is something wrong with me."
That distinction matters because shame can be especially painful. Rather than encouraging someone to repair a mistake, shame often leads people to withdraw, hide, or believe they are fundamentally flawed.
Outside psychedelic research, shame has been linked to depression, trauma, addiction, eating disorders, and many other mental health challenges. Yet until now, very little research had examined how shame appears during psychedelic experiences.
Why might psilocybin bring shame to the surface?
The study was not designed to determine exactly why shame emerges.
However, psychedelics often reduce habitual patterns of avoidance while increasing emotional access and autobiographical memory. Experiences, memories, or beliefs that normally stay outside awareness may become much more vivid.
For some people, this can mean confronting painful experiences that have been carried for years.
These moments are rarely comfortable.
But they may also create opportunities to understand those experiences differently.
Working through shame mattered more than simply experiencing it
One of the study's most interesting findings was that simply experiencing shame did not predict how people were doing weeks later.
Instead, what mattered was whether participants felt they were able to work through those feelings constructively during the experience.
People who reported being able to process shame more effectively generally reported better psychological well-being 2 to 4 weeks later.
This finding reinforces something many therapists and integration specialists have observed for years.
The goal is not necessarily to avoid difficult emotions.
The goal is learning how to move through them safely and meaningfully.
Psilocybin did not affect everyone the same way
Looking across the entire group, participants experienced a small but statistically significant reduction in trait shame, a person's general tendency to experience shame in everyday life.
Those improvements were still present 2 to 3 months later.
At the same time, the results remind us that psychedelic experiences are highly individual.
Nearly 30% of participants actually experienced increases in trait shame following their experience.
This is one reason psychedelic experiences should never be viewed as guaranteed healing experiences.
The same experience may lead one person toward growth while leaving another with unresolved emotional challenges.
What this means for preparation and integration
These findings have practical implications for anyone considering psilocybin.
Preparation often focuses on expectations around visual effects, mystical experiences, or difficult moments involving fear. This research suggests another possibility deserves attention.
People may unexpectedly encounter deeply personal feelings of shame.
Knowing that this is possible does not mean it will happen.
It also does not mean something has gone wrong if it does.
Rather, recognizing shame as a potential part of the experience may help people approach these moments with curiosity instead of immediately viewing them as a sign of failure.
Integration may be especially important when these emotions arise. Having time, space, and appropriate support to reflect on difficult experiences could influence how those experiences affect well-being in the weeks that follow.
Why this research matters
Modern psychedelic research has greatly expanded our understanding of depression, PTSD, addiction, and other clinical outcomes. Much less attention has been given to the specific emotions people experience during psychedelic journeys.
This study helps fill that gap.
Rather than treating all challenging experiences as the same, it highlights shame as its own important area of study. Understanding these experiences more clearly may ultimately improve preparation, integration, and future clinical care.
As psychedelic research continues to grow, studies like this remind us that healing is rarely about pursuing only pleasant emotions.
Sometimes growth begins when difficult emotions finally have a chance to be seen.
