So you both drank and he touched you when you were asleep and you want to know if he likes you. First of all, in some circles when a guy touches you while you're asleep, that's known as assault. It's a little creepy. It's also a little weak. This guy not only cannot make a move when he's not drunk, but he also can't make a move when you're conscious. Sounds to me like you're going to have to take control of this thing and find out whether he likes you or not by asking him out or just being direct. That said, a guy likes you when he's willing to make a move when he's not drunk and you're both awake.
