Psychedelics often produce a rich, intricate, and dynamic experience that is challenging to capture effectively. This chapter explores the essential phenomenological features of psychedelic experiences, emphasizing elements with potential implications for religious practices. I will start by highlighting the key aspects of mystical experiences commonly associated with psychedelic use. Following that, I will examine reports of encounters with God or other supernatural entities induced by psychedelics. Next, I will examine the “death experiences” and their lasting effects that some individuals report following psychedelic use. Subsequently, I will explore the potential of psychedelics as tools for changing beliefs, particularly concerning metaphysical beliefs. Finally, I will briefly review the overall impact of psychedelics on cognition, behavior, and social interactions. I will conclude by discussing the controversies and philosophical questions that emerge when interpreting the content of psychedelic experiences. Overall, I aim to provide a comprehensive analysis of the subjective effects of psychedelics and their potential implications for religious practices.
