Last night I went to sleep in my own bed and woke up some hours later in Charles's, with no memory at all of getting there. In fact, for a disoriented moment or two I thought I was in my bed, and Tony had brought Charles into it, until I reached out for something (my watch?) and worked out which room I was in.

I don't know what time it was I woke up, because my sleepwalking self left my watch in the other room, but it was still dark. Charles snuggled against me and we both dozed off again. Later on I woke up properly and it was morning.

I expect it wasn't truly sleepwalking, but just never waking up enough to actually lay down a long-term memory. A bit freaky though.
