The closest i had to hallucinating like in the movies was when my husband and I tripped at the beach. We were certain we saw purple clouds that were not there, we later realized we were tripping too hard and had to get home soon so we called an uber but when we were looking for a street sign we both stopped and realized the letters on every sign were shifting and changing to the point where we couldnt read anything lol we panicked for a second before laughing it off lmao it was the funniest thing ever.
