So i come into work for the past 2 day early, not really early just on time. No one else is here and for some reason i hear rustling going on in the back room. i Go back and for some reason hear children playing down the hall way. I go down there scared as fuck, and there is nothing there. Nothing has been moved from where it was the night before... nothing changed. i usually don't believe in the supernatural, but i REALLY don't know in this situation. For when i sit down again i can hear it, it's just laughing (like they are playing on swings or something) and just happy little kids. Strange eh?
