He just...touched me...please help! ?

Oh my gosh, some of my friends and I were hanging out, and this guy that I don't know all that well was there. It was kinda chilly outside, so we all went back to my house and hung out in the basement and watched a movie. He sat by me (we were all kind of strewn over the couch and floor) and at a scary part he kind of scooted closer to me, and by the middle of the movie he was REALLY close to me. Like, practically on me! but there were like 7 of us on the couch... and then when we all hugged goodbye, he hugged me REAL close from behind, and his head was close to my chest. Is this really odd? I'm not sure what I think about it!
