My story happened at my grandma’s house. My parents were going through a hard time. It was the time just before they filed for divorce and my mom thought that living with her mom would help her, so that was where we were living. I had to be eight or nine at the time, because I was losing teeth. I slept in the basement in a little nook that was curtained off from my parents’ room. My little sister and I shared a bunk bed. I slept on top because she was just a small girl and we were afraid of her falling. I remember hating the basement in my grandma’s house, and to this day I still do. I hated being there alone, but usually had to be if I wanted something from my "room". Whenever I was alone and I had to go back upstairs, I would run up the stairs as quickly as my legs could carry me. I always got this feeling in the back of my knees and legs and even my lower back. It was as if someone were about to grab me and pull me back into the basement. Anyway, I didn’t like that basement one bit.The day that my incident happened, I remember that I had just lost one of my teeth and I was excited to put the tooth under my pillow and get some money or a treat from the tooth fairy. After readying for bed and saying goodnight to my family and being tucked in, I put my tooth under my pillow. I’ve had this problem of not being able to sleep very well since as long as I can remember. It comes and goes very spontaneously, but it keeps me up when it does come. I have bursts of energy and can’t sleep a wink. That night, I was having that problem of not being able to sleep and kept looking out my window for the tooth fairy. Keep in mind that this was a basement window with a window well and everything, making it impossible for light to come in. I was so busy looking out my window that I didn’t see what was about to happen until it was nearly upon me.This green light was coming towards me, floating in mid air. It was almost a sphere, but not quite. It was glowing faintly with a soft neon green glow.
