Nightmare!!!!?

Ok the weirdest thing happened to me last night. I kept having this dream (nightmare) where i was lying in bed with my boyfriend and I would roll over and ask him a question and he would answer the question with an answer that I did not like. I would become enraged and start biting his face and things of this nature. Weird thing is (as if that's not weird enuff) he would behave as if I weren't doing a thing to him. I would dream that and then I would wake up almost sitting up with my mouth open and a hideous scream wanting to come from my throat but nothing came out but some odd groan that i could hear as soon as I woke up. I would go back to sleep immediately and dream the same dream but with variations and wake up doing the exact same thing. I don't understand it because it wasn't as if what i was dreaming was "scary" but you would think I had just had a horrific nightmare. I finally woke him up and asked him THE QUESTION.. and he answered it in the right way..
