Hallucinations are very diverse, but IMEs always follow a similar scenario.
Summary
Hallucinations are extremely varied, with each subject drawing on his or her most intimate experiences to create memories and fantasies that form a unique delirium.
On the other hand, the same phases, the same typical sequence - albeit sometimes incomplete, but unambiguously recognizable - can be found in every IME, however different the experiencers may be.Quotes
“When facing death (or thinking they are), some people may experience phenomena known as Near Death Experiences (NDEs). According to Greyson (1), NDEs are "profound psychological events, with mystical and transcendental elements, typically occurring in individuals close to death or in situations of psychological or emotional danger. These elements include ineffability, a sense that the experience transcends the personal ego, and an experience of union with divine or higher principles." Seeing a tunnel and a bright light, having a sense of well-being and peace, or seeing one's life flash by are relatively recurrent features of near-death experiences (1). Another frequently associated phenomenon is "Out-of-Body Experiences" (OBEs), i.e. an experience during which the person has the impression of seeing themselves outside their body, often from an elevated position (Fig. 2). Although the interpretation of these phenomena varies according to religion or belief, the characteristics of NDEs appear to be constant across different cultures (2).”
