A psychological interpretation of your dream is going to ask you who this man is. In the deam he has a face and you feel like you know him, but when you wake up his face vanishes from memory. In this scenario, your inability to recall his face sounds like a classic case of repression. I side with the psychological interpretation - for one reason primarily. And in your case - your paralysis strikes when you are actively confronting a person whom you are angry at.
Likely targets are fathers, boyfriends and bosses - or perhaps men in relationships more generally.
If you find this interpretation rings a bell, I suggest you reconsider your involvement with whomever the dream concerns. In no way are these sites intended to substitute for the professional services of a medical doctor.
