Things You Do In Your Sleep

SO I am not one to do alot of talking or walking in my sleep but a few strange things have happened lately. One morning I woke up with my sweatshirt in my hands. I wore my sweatshirt to bed and I had NO recollection of sitting up and taking it off because I was warm. HMMMMMMMM????? Then the other night I decided to roll over and pick up my cell phone. NO ring or nothing but I pick it up and a voice starts talking. It was so weird because I did not hear it ring or light up. Strange what we sometimes do in our sleep. What do you guys do? Come on we all have to have something goofy to share? :)
