regardless of wether youre a girl or a guy, its a still a fairly wierd thing for a friend to do.. id guess he has a few things he needs to talk over with someone..
not sure if it was bravery or stupidity that lead him to beleive he could do all that and not wake you up mind you. its not exactly subtle. Not much you can do except challenge him about it, or just avoid it and make sure you never sleep in the same room as him again.
