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.
8. Do you dream?
No, or I don’t recall them. I’ve had a couple dreams but there was no visual or sensory component to them. When I woke up, I just knew a list of “plot points” about things that happened. This is also how I digest fiction.
Ah thanks, I missed this one when reading the article. Some other commenter talks about having a coworker with aphantasia but still being able to dream so they may well be a whole spectrum of what people can / cannot visualize.
I would be surprised if you weren't capable of "seeing" the typical colorful geometric patterns of a DMT not-quite-breakthrough with your eyes closed, and the experience of having something pass through your mind's eye just once might trigger dormant pathways.
Anyway, as a quasi-professional, my advice if you were going to pick just one to try, would be vaporized freebase DMT.
If you ever do (and I'm not encouraging you to do so) please document it!
