There was this girl who the main characters (all 20s-30s, mixed gender) were friends with, but really she was a person-eating, shape-shifting monster. And she kept trying to get everybody to go somewhere alone with her so she could eat them, but rather than be mean about it, the conversations would invariably go:
"Hey can you come over here for a second? I really need to talk to you."
"Do you really need to talk? Or are you going to eat me?"
"... Talk?"
"Come on, Helen, we've talked about this before."
"I know! I just get so hungry!"
And so on.
I don't really know the plot, but the monster ate her husband, who was the pilot flying the plane they were both on and then the rest of the dream happened in bullet time as the spirits of various people communicated with each other while the plane slowly crashed into Cincinnati.
It was weird. I never saw the ending
