i am a little long winded today
lol well put Dwid. There are those that have a condition called a slow wave sleep disorder and are very "active" sleepers but they are the exception. In the majority od people the muscles paralyze as the brain waves speed up during the REM cycle (except, of course the involuntary mucles). There is a segment of the population that instead of the brain waves speeding up they slow down allowing the voluntary muscles to move. The condition usually isn't serious. but i used to date this girl for a bunch of years that had it. She used to sleep with her eyes open, sleep walk, sleep talk, but more alarming sleep punch. mostly the walls but sometimes me. (at least she said she was sleeping lol). but it was weird. she also had a tendency to scratch herself.
anyway as for the actual topic of this forum i have been debating whether i wanted to weigh in. Just because a person hallucinates does not mean they are schizophrenic, though it is one of the most obvious clinical signs. There are 4 symptoms that constitute schizophrenia, flattened or inappropriate affect (emotion), hallucinations (almost always auditory but occasionally visual), delusions (paranoia, grandeur, persecution being the most common themes), and and unexplanable incommunicability (either they don't make any sense when they talk or they can't process what they are hearing). Now any of these individual symptoms can be explained by other circumstances (perhaps head trauma, a tumor, brain lesion, etc). what really sets a schizophrenic apart is the idea of insight into their illness. a schizophrenic does not realize what they are experiencing isn't real. even when they are told that. so jumping to a conclusion as significant as that is risky. also there is a condition known as schizophreneform (spell check) disorder which looks a lot like schizophrenia but unlike schizophrenia isn't a permanent disorder. it usually lasts about 6 months to a year. i guess its the difference between being chronic and accute.
now whether this individual is able to discern that the hallucinations are real or not could go a long way to determine what is going on. whether the demons are real is a religious/ philosophical debate i have no intention of even touching.
so with all of that said the only person that is going to be able to determine the mental well being (or not so well being) is a qualified physician. sure somethings are able to be dealt with on a faith base but other things need professional consultation. this does not mean this person is "crazy" it just means there is someone more qualified that can assist him/her.
sorry for being long winded.
