Last night i had multiple dreams where i woke up and remembed them, however the last one sort of rised an interesting question and i am looking for some input.

I was in my house on the coutch with a girl, the girl was someone that i know semi-well, anyways, we were sort of cudling and what not (note: this sort of thing wouldnt have happened with her), so i told her 'you know this is just a dream and nothing is real' after i said that she or i turned a little, i think it was her, and then she sort of had this crease in her face, well maybe it wasnt a crease, but it was definatly a line down the centre of her face, i kept on looking at her for a few seconds then i woke up, as i opened my eyes in the realitve position of her face and the line was my blanket, and the line was the end of the blanket and the beginning of the wall (the wall was a few feet away, but the wall is what i could see after the blanket).

I guess my question is what was going on, was it that reality and the dream world crossed over? Is that what was happening? I know it was just a line but both experiences, being with her and waking up in my bed were so real, it was intesnse.
