I always felt like I was hallucinating, but instead of my eyes seeing stuff except for patterns occasionally, it was my mind's eye. When I go somewhere in my mind's eye, the picture is more vivid than real life so I sometimes get confused for a second which one I'm in. I always thought that if your eyes saw the stuff you would die because you would be doing stuff like if you actually were a 10 year old at the circus in your mind. I'm high so I don't know if that made sense.
