ok dudes i think this was scary cuz it happened to me.. it was a couple years ago,and me and my sister were chasing each other around the house and i could have sworn i seen her go upstairs into our room,so i ran upstairs into the room,but i dident bother to turn on the bedroom light cuz i was sure she was in there and i would find her,so i jumped on my bed of all fours i was hyper so i dident care that i was in the dark..but then i saw this white oval sway past me it was pretty long,i followed it with my head and then i think it disappeared (i cant really remember cuz it was a long time ago)...so then i ran downstairs to the living room and i see my sister with my dad on the couch watching tv. I asked her if she went upstairs at all and she said "no" puzzled and said "i've been down here the whole time" God i was so scared after that!
