Okay, I might as well jump into this dream
The part of last night's dream I can remember is rather short. I was talking with two people who in real life I'm not especially friends with, but in this dream they were friends, and I made some off-handed comment that I thought was semi-witty, to lighten up the conversation.
The conversation stopped dead, and one of the friends said in a condescending, sarcastic voice:
"FUNNY! Ha, ha, ha, ha... no."
The "ha"'s were punctuated, forced-out mockeries of actual laughter. The other "friend" joined in halfway through the "ha"'s. As my dream self became extremely embarrased, I remembered who these people were in real life, that they weren't actually my friends, and I woke up.
