I had the itchy bugs all over my skin sensation the whole of Friday and man it sucks. I don't have an answer for your bed being slapped. I've had strange things happen occasionally when I'm home alone too and I've thought huh? Funny thing is, it's been while I'm in bed too. Wonder if it has something to do with us partially nodding off but feeling awake then being fully awake and not realising that for a few seconds we were nodding.
