Who?

I woke up after another semi-sleepless night and another dream, this time I recall little detail except it involved K and us having lots of sex (though the context escapes me), and another vaguely identified woman who featured in only a small way. I can't remember exactly who it was, but like Melanie's appearance a few nights ago, it was someone I knew, but wasn't particularly close to, nor was in current contact with. An old school crush maybe? Someone like that.
