I hate when psychadelics are misrepresented to people who haven't taken them. For the best depiction I've seen, Fear and Loathing in Las Vegas: the carpet in the hotel lobby and the cross-bleed of the war reporting on television and how he felt about the photographer talking about motorcycles (it's not literal, for those who aren't experienced).
You've never taken LSD and had your conciseness split into several crocodiles that are being petted by an old granny who thinks she is a duck (and all of you love her)??
