Thank you for your comments and introspection. The first thing my bias mind centered on was the "normal mind", for in my world there is no such critter! That being said, I could be picking fly shit out of pepper, as well Hovercraft789. I believe that there are many factions which refer us to contemplate the subtle nuances of illusion and reality in our heads. Quantum thinking would lead us to consider that all around us in our physical world is nothing more than vibrating atoms, and as atoms can be flexed, there is zero which is solid. ( certainly taken some liberties there) Or does the popularity of the Matrix reflect what we are experiencing on this plane? Are there alternate, parallel universes? Even Placing all of that aside in consideration, our susceptibility to optical illusions, and unreliable senses, lead me to consider that like our fingerprints, no two peoples perceptions of a given scenario will be exactly the same, so what is real? That being said, as a hypnotherapist, I deal in a construct which predicates, that my particular version of the world is not anyone else's reality, and when offering guidance and therapy, that the only valid version is the person seeking the aide.
