What would 당신 do if ......

ask how drunk I was

I'd just stare and ask "w-what are 당신 doing?! Who are you?!"

Me: Could 당신 please move?
You: ..... *moves out of the way*
Me: Thanks *sits Down on my 침대 and starts drawing
You: W-what....
Me: *Waves my hand at you* 당신 can leave now

Probably scream, haha, sorry but I would probably be really scared that there is a person in my bed.

Probably start yelling at 당신 about how 당신 are getting your germs all over my bed. (Germaphobe)
