alt Hacker NewsContrary to popular belief not all delusions and hallucinations are horrifying. Similarly, not all of them compel people to do bad things. There are cases of schizophrenics who had voices and hallucinations telling them to be good to people and go out of their way to help strangers. There's definitely all sorts though it's not like one or the other or that a person only has one type.
If I'm very tired (after I had insomnia for two or so days) I have mild hallucinations, and they're pretty boring/benign. But mine are more auditory than visual.
This isn't unusual when people are sleep deprived though. I think lots of people just don't realise they are hallucinating in that state
