It only took me one trip on dissociatives to realise how much my sensory experience is dependent on small changes in my brain chemistry. Kind of shattered the illusion of reality being this stable, objective thing. Everyone is different and it makes sense therefore that their subjective experience of reality is at least somewhat different to mine.

Even from a physics perspective we know that what we experience is at best an approximation of reality. Vision is basically just radar with high resolution. There’s a lot missing.
