After watching the movie "A Beautiful Mind," I've wondered about the correlation between dream characters and schizophrenia. Although a friend of mine who treats patients with this disorder stated that the movie highly exaggerates the notion of imaginary characters, some of the concepts depicted are actually accurate.

Here's my question for anyone with knowledge on this subject: Are the imaginary characters encountered by schizophrenia patients similar to dream characters with only difference is one is able to be experienced during waking life while the other during the dream state?

It would seem logical since in both cases since the mind cannot tell the difference between real and self-created people (with the exception of LD). It may be the case where the mechanism in the brain responsible for simulating a reality or acheiving a "dream state" is being activated during the waking state for people experiencing schizophrenia.

On a side note, this same friend who treats schizophrenia is probaly the only person outside of this message board I could have deep conversations with. Other people are either highly disinterested or even irritated (like my wife) in these "weird" topics. He even discussed with me the far-fetched possibility that the characters experienced by schizophrenia patients are NOT created, but instead a gift or ability to see outside of the physical world. While both of us weren't completely serious with this theory, it was interesting talking about the possibility of DC's and "imaginary" characters being actual people.
