Permanently affected perception (vivid dreams, hallucinations) even off cannabis?

I'd been an avid toker for a few months this early summer, so not for long, but I was incredibly taken aback.

I haven't smoked for weeks though as I guessed my general perception and outlook of life seems more lucid to me. The vividness of my dreams and my ability to visualize has increased dramatically, probably permanently. My sphere of general enjoyment feels like it has a greater expanse due to a general vibrancy and attention to details. Music is amazing. My dreams become experiences; many times, it becomes difficult for me to tell the difference between dreams and reality, and sleep paralysis occurs much more often.

I feel gracious for this, at some times disconnected despite an underlying feeling of unity with my surroundings. As a little background, I suffered (and still do) from depression and dissociation.

While under the effects of cannabis, I frequently hallucinated or experienced extremely skewed "sloppy-dead" proportions, sometimes to the point of seeing form constants (my view swirled into an array of colors) or feeling like I regressed to the time in which I was a young child (dreamy, feeling fond and absorbing my surroundings with immense sensitivity). I was usually very, very paranoid about other people in my surroundings and how I look to others when I'm high. I suspected possibility of schizoaffective disorder, considering my background, and the fact that marijuana seemingly triggers a greater frequency of hallucinations. I can imagine or recall music extremely well, and get caught up in it just by thinking of it, and have gotten to the point of hallucinating music (not voices!) which is extremely pleasant. Fortunately, I'm channeled my emotions and energy to positivity, so I am not entirely freaking out.

One thing I consider not ideal for maintaining a stable academic life in college is the fact that sometimes while relaxed, my vision starts to zoom in and out as if I was high. This occurred most prominently when I was listening to a speech in my college, to the speaker whose voice sounded hypnotic and essentially threw me into a trance. Weird.
In addition, my memory in general has been poor since I feel as though the distinctions between dreams and reality has blurred, My cognitive word associations have broken down, so I am more incomprehensible with my speaking.

In general, I feel as though I've been in touch with the "collective unconscious," sort of like how many LSD users seem to experience similar hallucinations. It's as though I experience some telepathy and generally have been feeling overpowering ESP (which I never really considered plausible until recently). I've been able to predict strange things or answers and my predictions are consistently correct, but what really gets to me is that in some of these instances, my perception feels fine-tuned and the moment seems frozen in time.

I imagine that many of the users here continued consistent use of marijuana and I understand that people experience a variety of different effects. However, for those who stopped briefly or do not smoke now, have you experienced these a greater perception or strange, seemingly omniscient feelings?
