Whenever I start playing a new game, I dream about it once. Like, when I started playing Diablo 2, I dreamed I was hacking my way through skeletons. Then, when I started playing Dynasty Warriors 4, I dreamed that I was fighting some people in a park and life bars sprang up over their heads.
I've only had one D&D style dream, and that involved me in my +3 Plate Mail, Cloak of Displacement, and Frost Brand (back when those were Bastard Swords, thank you) fighting a pair of thugs and a sinister black-armored figure. I think I showed a rather surprising amount of sense, too; I whacked one of the thugs' axe after he swung at me, threw him over my back, stabbed him with my sword, sat down, and woke the heck up. After all, I know I don't know how to fight, so running was the best solution.
