Several of the hallucinations described can be reached by meditating. And there are hallucination types due to drugs that aren't in there. I've seen crazy stuff, like people's neck stretching for tens of meters and their head coming right in front me although they were on the other side of the street. I did stop taking drugs, nearly 20 years ago, after that one did happen to me. I still do meditate that said.
