S3 - Confused

This morning I woke up on the floor of my living room. Naked. I can't remember what happened last night. I was here, in my apartment. It's not like I was out anywhere and something bad happened. I just don't know how I ended up on the floor without any clothes on.

There's something else. The window was open when I woke up, the big one above my desk. I don't know how that happened either. My apartment is on the seventh floor, so it's not a convenient entrance or exit.

Maybe I was sleep walking. I've never done that before, as far as I know. But that kind of thing can start randomly, right?

Anyway, I took a shower and got dressed for work. I just wanted to write down what happened before I left.
