About this trial

The purpose of this study is to assess the effects of 5-HT1A receptor blockade on the acute subjective effects of psilocybin, as measured through subjective survey measures and acute electroencephalography (EEG). Further, the investigators will assess the effects of psilocybin on post-acute sleep and dreaming through the use of sleep EEG and sleep and dream diaries.
