So you cannot visualize things while trying to but do you dream at night ?

About psychedelic drugs, it's not something I would advocate lightly as it has the potential to mess you up pretty badly. From my limited experience it was more like having my imagination on steroids so I wouldn't know what happens if there's nothing to enhance in the first place... That said I've never taken hardcore stuff like lsd or dmt where some people report having full visual hallucinations.
