I never hallucinated after trying shrooms, even at high doses. I found this odd, since I have read about countless people saying they saw stuff that wasn't there or saw colorful fractal geometry.
So my conclusion is that shrooms simply increased my perception and allowed in more information, and that all this fractal geometry is already there, just waiting to be discovered.
It's just like tuning into a higher frequency. It's not fake or generated by the brain, simply observed for what it is.
I think it really depends on the type of lsd/shroom.
Myself and some friends recently came into a new batch of acid. I don't usually have major visuals but with this batch I really do, and so does everyone else who takes it. Eyes open and the whole room has turned into a beautiful shifting geometric fractal pattern. When I closed my eyes it was even more intense, incredibly colorful, beautiful, sexual, shifting fractal geometries. It really felt like I had stepped into one of those AI art generators except far more coherent and personally meaningful.
Also I had the opportunity to try DMT a few months ago and that really did take me to another reality (not literally of course). Incredible, beautiful multi-sensory experience that I won't try to explain here, however the visual and auditory components were extremely intense.
I don’t think either LSD or Shrooms causes hallucinations (like seeing a creature that isn’t there.) Mushrooms make me feel strange and see a bit blurry but it’s mostly an internal thing and makes my wind wander. LSD is a bit more intense, visually, like colors become more vibrant and my mind creates detail in even the simplest of items (peeing in the toilet damn near gives me a panic attack.) I’ve only ever heard of people seeing things in movies other than maybe sitting in the dark and seeing “demons” but my mind does that already by trying to give forms to the visual noise of darkness; again just not as intense.
Typically “movie” hallucinations like seeing elephants in the room or having strange people visit you or seeing bugs all over you are more typical of deleriants like diphenhydramine or datura, although high dose tryptamines can be so strong that there is no connection to the reality around you - overwhelmingly psychedelic. In that state hallucinations of a different type are possible (talking to entities, being somewhere else entirely, etc.) Movies are a very bad representation of psychedelics generally, though.
Maybe a stupid question but did you close your eyes?
I think you need a really high dose to see more than a bit of distortion when you have your eyes open. But with you eyes closed, your mind can run wild, making colorful visual much more likely in fact, you may not even need drugs for that.
Seeing things that aren't here, true hallucinations, don't happen often with psychedelics, and they are mostly caused by deliriants (ex: datura), or body reactions like fever. These are not fun and deliriants are not controlled substance for that reason, being classified as poisons instead. Psychedelics cause pseudohallucinations, it means they alter your perception but you are aware that what you are seeing is not real.
So my conclusion is that shrooms simply increased my perception and allowed in more information, and that all this fractal geometry is already there, just waiting to be discovered.
