A childhood belief about monsters

Since I could remember, I had lived in one room, sharing it with my sister. But one summer, we put an addition on our house - two rooms, one for my sister, and one for me.
Therefore, we had to go out and buy beds. My mother found a cheap one, used, that just happened to be about four feet high.
My bed was nestled into a corner of my room and left a hefty crack between my bed and the wall. That freaked me out. I couldn't stop imagining a pair of long, green fingers crawling out and grabbing me in the middle of the night.
So I spent many a night, huddled up against the opposite side of my bed - not even daring to look at the crevace and would often end up in the morning with a bloody nose on the floor, smothered against my doll, one foot stretching one hundred degrees upward caught on my blanket (I think this position contributed to my flexibility in my yoga classes) and often enough a pool of druel against my cheek.
