Its like switching from only eating red meat to being a vegan. Its a total paradigm change. Down is up, dry is wet, day is night. Instead of breathing in oxygen and exhaling carbon dioxide (like i know), you have to make like a tree and start accepting sunlight and creating oxygen. Wear your shoes on the wrong feet, socks on your hands, underwear out. But act like everything is the same, everything is normal, while you're dancing on the ceiling.
