I'm wondering whether autistic people can have similar hallucinations that psychotic ill people can have - such as auditory voices, faces appearing in objects that otherwise would not look like faces, paranoia, delusions and etc.

Also, how does a psychiatrist medically distinguish between a type of psychosis and a type of autism when they're so similar, apart from brain examination (if such even exist for these things)?

Wondering because I show signs of autism as well as signs of schizophrenia.
