00:00Hallucinations have long been used in movies to portray different types of mental illnesses,
00:08with horrifying themes often being front and center.
00:11However, the reality of how hallucinations more often manifest in the real world is quite
00:15different 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
00:25can also often involve feeling something.
00:27Experts say that sometimes a hallucination might include feeling something crawling on
00:31one's skin, and what are called gustatory hallucinations involve tasting or smelling
00:35something that isn't there.
00:36In film, hallucinations are most often portrayed as a symptom of schizophrenia, but there are
00:41actually 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
00:49these types of events, with upwards of 75% of those with Parkinson's experiencing visual,
00:55auditory, and tactile hallucinations.
00:58Experts write for The Conversation that hallucinations can also be triggered by extreme grief and
01:02by sleep or sensory deprivation.
