In the same dream I ran into one of my disliked ex-roommates. I said something, mean but truthful, I can't remember what, and then, "Oh, I miss you!" I lied, and gave her a hug. This is the only time I can remember being deliberatly dishonest is a dream, and for some reason it really bothers me. Probably because if I saw this person in real life there's no way I'd give her a hug.

In my dream this morning my skin started breaking out in warts in like, 5 different places. "But I can't afford to go to the dermatologist!" I wailed.
