Please help me i've gone deaf in one ear!

Ok its about 4am here. Several hours ago I got up from lying on my couch and i couldnt hear anything in one of my ears. I have quite long hair which covers my ears so I must just not have noticed while i was lying down. After jamming my finger in there a bit, there was a bit of dried blood in it.

I'm kind of panicking but I dont want to wake anyone in the middle of the night if its just some water or something, so what better place to come than OOT.

So anyone know about this sort of thing? I'm only 22 yrs old and never had anything like this before (apart from for a few minutes sometimes if water in ear)!
