Sleepwalking

So I've caught myself sleepwalking twice now. I've not yet left my bedroom while asleep, but it's still cause for a bit of concern.

I've no idea why now, or if it's indeed a new thing. It has been happening since I got back from Australia, and I did feel some kind of internal change from that trip so perhaps it's to do with that.

Otherwise maybe it's something mundane like having too much on my mind or not getting enough sleep. Whatever the case, I just hope I don't end up walking in front of a bus or something...
