dream on dreamer

On Saturday night I dreamed that I was taking care of 3 bunnies.. It felt like one of those long dreams with very complex other bits to it. The last of it was me carrying 2 of the bunnies and looking for one that was hiding. All of a sudden one of the bunnies I was carrying started biting my neck but it didn't hurt just felt like a pressure. But then I felt something biting my bum! And that hurt - a lot! It was like a long pressure pain then and OWW!! At that point I woke up thinking that the missing bunny had bitten me, only to find there was a mosquito in the room and I now had a lovely bite on my bum (It was hot - who needs blankets!) Anyway, the thing is, that apparently dreams are just seconds long, and therefore my dream was probably a reaction to the bite ie my mind had to make up a story to match the pain I felt in reality. So this leaves the question - why the hell was I dreaming about psycho bunnies?!
