Once, I exited the house, and tried to press the hotkey (shift+space) for my mount. I've had of similar WoW-related escapades, too many to remember any particular apart from that one. Might've been my first.
And I use Keelah instead of God whenever I'd say "oh my god" or things along those lines. That's concious, mind you.
Also, I once fell asleep during a lecture, and dreamt I was Garrus, sniping some mercenaries. When a friend woke me up, first thing to come out of my mouth was "Can it wait for a bit, I'm in the middle of some calibrations...". I shit you not.
