I was just watching Empire and I realized something strange. People may have noticed this but it's the first time it occurred to me. At the beginning when Luke is hanging up side down and he wakes up. Can he really wake up that way?

Here is what I'm thinking. If enough blood rushes to your head you can pass out. (I could be wrong) Luke was knocked unconscious before he was hung upside down. Now with all the blood rushing to his head while unconscious like that, is it possible to regain consciousness from that position?

I don't know, I'm not a doctor. Any thoughts on this matter?
