I dreamed last night of lying in bed with someone who was a patchwork androgyne of two lovers of mine, with both their memories. It took me some while on waking to realize this fact; in the dream I had mostly noticed the presence of each by turns, except for the scars.

I had a dream very like this about 8 years ago, where I woke and realized that while the dream lover had been one person, zie very clearly had someone else's scars.
