The study looked at how our sense of self can change in conditions like psychosis and under the influence of psychedelics. They tested people with psychosis, those who have used psychedelics, and a control group to see how their sense of self was affected. The results showed that people with psychosis had trouble feeling like their body belonged to them and controlling their actions. People who had used psychedelics reported long-lasting changes in their sense of self, but these changes didn't affect how they felt about their bodies. This suggests that psychedelics can change how we see ourselves, but not necessarily how we feel in our bodies.
