head trip

i was holding a baby last night, not my own, while lying on my bed. The infant frees itself from my grips and falls down the side of the bed which rests by the wall. I quickly look down and it's all dark almost like a chasm. I jump out of bed in a panic and turn on the light then with a quick reflex move the bed. i suddenly wake up standing exactly where i was in my sleep with a flux of realization.
