00:04Hallucinations have long been used in movies to portray different types of mental illnesses with horrifying themes often being front
00:10and center.
00:11However, the reality of how hallucinations more often manifest in the real world is quite different from what Hollywood depicts.
00:17First off, hallucinations can manifest within any of the five senses.
00:20The usual tropes of seeing images or hearing voices is no doubt real, but hallucinations can also often involve feeling
00:26something.
00:27Experts say that sometimes a hallucination might include feeling something crawling on one's skin,
00:31and what are called gestatory hallucinations involve tasting or smelling something that isn't there.
00:36In film, hallucinations are most often portrayed as a symptom of schizophrenia,
00:40but there are actually a myriad of issues that can be precursors to having these phantom experiences.
00:45Having a high fever can be one, but experts say that Parkinson's disease also includes these types of events,
00:50with upwards of 75% of those with Parkinson's experiencing visual, auditory, and tactile hallucinations.
00:57Experts write for the conversation that hallucinations can also be triggered by extreme grief and by sleep or sensory deprivation.
