Touched by an angel???

Last night I fell asleep on the couch in the basement watching TV, which is not unusual. I remember laying down and I remember the point I fell asleep. At that time I did not have any covering on me. I remember waking up briefly around 2am and was not covered. I woke up at 5am and was totally confused because the blanket was covering me. There was no one here except my sister-in-law and myself (and the two cats). I could tell by the way the blanket laying that someone or something else had covered me.

I've been doing a lot of reading about angels lately and feel drawn to work with them. I've recieved a few messages which I attribute to them, but this is the first tangible evidence I've had of their being around.
