A dream

Last night I had a weird dream. I woke up and found over 9 billion people were missing. I then found an old friend form high school was one of the survivor and we went door to door looking for people and gathering supplies because we knew in about 3 to 5 days the power grid would start to fail. During my dream we learn that the missing people were abducted by aliens by targeting a specific gene sequence. Just as I learn that my entire family except me were taken, that's when I was awoken by the middle saying that she had a bad dream. How is it, that someone so small can take up over half the bed and always, no matter what position you or they are in, able to poke you with razor sharp knee or elbow? I mean she is only 3'3" tall and weighs 35lbs. the physics are mind boggling, I am twice her height and about 7.5 times her weight. It has to be those knees and elbows, that is the only conclusion I can come up with. The moral of this story is, do not watch Kill Bill Vol. 1 (please note that the middle did not watch this movie) before going to bed.
