I was talking to one of my physics professors the other day about an idea I had. The idea implied that reality could be set up in such a way that quantum particles appear to exist as we know them to but actually don't. He said something about the improbability that this is all just one big trick, and I agreed that it certainly seemed to be completely real. His statement about improbability bothered me for the rest of the day - "why am I so obsessed with this notion that reality as I perceive it could be an illusion?".
It wasn't until later that night that I realized why my professors leanings were so different from mine. The exact realization was something along the lines of: "It's hard to imagine that reality as we know it could be one big trick if the only context for your imaginings is reality as we know it." I realized that the illusion is so perfect and so tight-knit that you would never even think to question it unless you had actually seen behind the curtain.
We are mystics, I guess.
Every day I am thankful that I was introduced to psychedelic drugs.
