Schizophrenia, yes, but that level of hallucinatory experience doesn't happen without demonic input.
Meh, the aural hallucination of a person crawling over a car and incessantly tapping on it is quite mild. All he actually heard was metal creaking and tapping, but he interpreted quite vividly as something else.
Pretty much the rest are textbook delusions.
Nothing extraordinary as far as mental illnesses go, so unless many schizophrenics are haunted by demons I see no reason to propose an extreme supernatural hypothesis here.
