I was babysitting two boys and they were upstairs, they had been asleep for like almost two hours. I was downstairs doing homework and all of a sudden behind me I hear little girls giggling. Not distant either, RIGHT behind me. I turn around half expecting Elias(the younger boy) to be there but he wasn't. At this point I'm really freaked out, the giggling continues but it sounds like its coming from another room now. I ran throughout the whole house and turned on all the lights. I had to call a friend to come over cause I was scared shitless.
