I get blinding surges of reality, ones that force me to be so introspective that I start feeling weird as a human being.  The only kind of example I can draw up is to imagine the word Refridgerator, and repeat it fifteen or twenty times, and realizing that refridgerator is a very, very weird fucking word.  It’s like an encyclopedia has been shot straight out of a cannon and hit me in the face, but instead of breaking my nose the encyclopedia makes me challenge all of the entries.
