Friend puts his feet in my face.?

its really creepy. whenever im with my friend and we have to share the same couch or i sleep on his couch thats shaped like an "L" he does something really creepy. once im asleep he like puts hes feet on my face. at first i thought it was just him and that he was asleep and everything so i moved his foot and fellback asleep. but then it happened again and i was a little weary, but i was really freaked out because i woke up and he had his toe in my mouth. i like freaked out and screamed and said i was disgusted and again i got the i was asleep sorry. and im just really freaked. why does he do this. is he really just sleeping and im freaking over nothing?
