Not surprising. I've only had this experience with DMT and am skeptical that it's perceptual rather than imaginary, but a) I couldn't think of a better way to describe it and b) it was really hard to ignore.
It's not something I've ever seen referred to in other people's reports, though I don't really keep up with research in this area. I have no hesitation in saying that DMT fundamentally altered my worldview though.
It's not something that strikes me as having hedonistic appeal. On the other hand it would be pretty drastic for an inexperienced tripper and imho better worked up with some less intense drugs. There are certainly 'smart' ways to structure drug experimentation and minimize risk, but it's important to feel comfortable about your consumption decisions precisely because drugs temporarily make your psyche more malleable.
