Yes, that does hold some resemblance to a psychedelic experience, perhaps not salvia though. Many psychedelics have some similarities in that closed eye visuals take on a kaleidoscope effect, often with repeating patterns, complex colours and depths, and avatars being present bei it a face, a figure or many eyes, animals or aliens.

Salvia divinorum is not a terribly thought provoking or spirit enhancing substance, instead it's confusing and disjointed with no particular recurring aspects that could be considered enjoyable or meaningful. I'd not say salvia was scary as such, but it's not something that induced any powerful emotional responses. Compared to tryptamines and psychedelic phenethylamines, salvia is one of the weirdest and most uncomfortable experiences one can decide to partake in even though it doesn't even last long.

On one occasion smoking 45x extract induced physical detachment, reversal of the sense of gravity, hot and cold flushes, and then complete visual detachment from reality. I was dragged to the left and had no choice but to lay on the floor and circle to the left as I felt like I was falling. I recall the tree outside becoming a painting that turned upside down and the entire room turning white and a giant piano with rolling waves of piano keys wooshed beneath me. The experience had no sound, no fear, no joy, no avatar, and no complex structured visualization. It ended as quickly as it started and resulted in feeling like my skin didn't fit right.

The human brain produces several powerful substances including DMT, it's no surprise that we sometimes have some odd dreams. Appreciate the oddness and find revelations in it if you wish, or just appreciate that the effect of chemicals on our subconscious are interesting as fuck.
