yes, that is the reason people take it because it puts you on extreme highs, although you also get extreme lows when you become addicted. if you are thinking of taking the drug, don't. it is very bad for you and all of the brain cells that are killed by the drug don't come back.
Simple answer. No.
If your dreaming about something like that its only because you are missing him or something like that.
If you want to get all nerdy with it then i'd have something to do with your subconscious mind.
