As a young adult in beginning of my 20s I've experimented with a plethora of other drugs as well, mostly psychedelics which back then were legally available, at least where I'm from (Ayahuasca is still legal here [1]).
Its been a good 10 years ago but during my experience with DMT + MAOI (self prepared, legally bought from a company called Azarius). From what I remember, I merely saw dragons in all kind of colours whilst lying down. I couldn't see through it just like you described. Auditory perception was vastly altered as well, akin to psilocybin, but with psilo I often lacked the visual aspect of 'tripping'.
The most anxious part of my consumption was the preparation because of the dangers associated with the MAOI. I carefully avoided everything except one cup of espresso a few hours before I started intake. I also didn't quit smoking (back then I was an average smoker). I had no hunger during my usage, though I don't remember the effect on my smoking habits. I wrote various trip reports for private usage back then and still have them, but either I didn't do it with the Ayahuasca one or it got lost.
In hindsight it wasn't very mature. I did extensive research on all of the drugs (A. muscaria was particularly fascinating) but did not always have a babysitter. I had a mild psychosis from cannabis at one point, and a few years later I was diagnosed with GAD and AvPD. Recently, this got reverted to a primary diagnosis of ASD (autism) instead. I also have schizophrenia in my family, though distant, and have memory problems. ASD has severe effects on sensitivity, thus could potentially be dangerous with psychedelics. Perhaps also worth noting that years after I quit recreative drugs usage I had one severe psychosis, triggered by stress.
This is absolutely true. I've seen a few movies recently with some self pronounced critics and we were amazed at how good the movies were that were rated horrifically low.
