Mattress

A bunch of excellent looking girls in cheerleader uniforms, who were really a college volleyball team, practiced in a half serious mood with hilarious Madonna- and Cyndi Lauper poses, and rounded the unsmiling fun off by pushing one of theirs through the hall in a wheelchair when they left the gymnasium. The girls who pushed the wheelchair bumped it into the legs of the one walking in front, and she began to complain and claim that she was injured now. A cut then showed her in another wheelchair alongside the first. I remember thinking vaguely how odd it was that that school had spare wheelchairs for shenanigans like this.

But none of that had any consequence at all when I got an extremely lovely girl into a room with a mattress. The room was new, somehow, newly renovated or something, and there were boxes standing around. There was also a second mattress.

It distracted me from what I was supposed to be doing on mine, because there was a naked back and bum on it. They removed themselves after a while - they belonged to a young man - and where they had lain facedown was an old woman. She sat up. She was stark naked, too. She was thin and had bright grey short hair. She looked at us with sort of a smirk. I think I asked her something and she replied, her explanation of the situation including something along the lines of: "He wants me to pretend I'm a board."

"What?"
"A board. A wooden plank."

"Why?" I was thoroughly perplexed. She shrugged.

"He likes it that way."

I suspect it was my utter blankness of mind at the realization that this young man got off on wooden boards which switched the dream off.
