I remember serious time slowdown - eg distortion of sound pitch, just like with slowed down grammaphone with overuse of cannabis back in the university times. It was interesting, but not pleasant. But I guess thats quite common thing for many drugs. Later on I have thought-trained myself to think of time of something arbitrary - I can more-less think of future and past to anytime I wish to. So distant pleasant memories are just as 5 min ago, and something unpleasant is consciously very far in past. It is like being able to time-travel, and it can be quite inspiring and revealing thing. Can be confusing also, I can see and feel myself as 25 years younger (as 20yr old) anytime, but the others probably dont.
