The transformative powers, science and culture of hallucinogenic substances.
Hallucinations are a type of sensory experience that occurs without any external stimulus. They can involve any of the senses, including sight, sound, smell, taste, and touch. Hallucinations can be a symptom of a variety of mental health conditions, including schizophrenia, bipolar disorder, and post-traumatic stress disorder (PTSD). They can also be caused by substance use, sleep deprivation, and other medical conditions. There are several different types of hallucinations, each with its own unique characteristics. Visual hallucinations involve seeing things that are not actually there, while auditory hallucinations involve hearing sounds or voices that are not present. Olfactory hallucinations involve smelling things that are not present, and gustatory hallucinations involve tasting things that are not there.Author(s): Georges Naasan*
