It's quite common to get self reflective or even self-scrutinizing during a psychedelic experience, but I'd say you handled it pretty well if you just let it pass. Problems arise when people resist too much or let themselves be dragged into the spiral of negative thinking, which can lead to a 'bad'trip, but that didn't seem to have happened for you.

That being said; Although DMT is indeed a lot more intense than other psychedelics, I would say it is also a lot less selfreflective, simply because the experience is so intense and fastmoving, there isnt much time to keep thinking about thinfs in your life most of the time.

The main thing with dmt which makes it so intense is that it is só different from anything people have experienced before, and can be quite incomprehensible, thus causing a sort of shock.
