I get incredibly weird and vivid dreams from Prednisone and I know a friend who was prescribed Benzo (not sure what kind) and also got very vivid dreams. I don't know if is the same type he describes but it is like a normal dream; just stronger and odder for me (with a completely different medication).

It is nothing like a psychedelic trip for me.

If you want to try and see if you get weird/strong dreams there are a lot of anecdotes around the supplement ZMA. It is just anecdotes but I've seen threads started on many different training forums from newbies asking about it.
