This isn't a long story or really scary as it is unsettling. This... Phenomenon took place in Delphos, Ohio around 3 am (can't remember exact date, but I know it was at least a year ago).
I was walking around with my 2 friends and my friends mom. We were helping her deliver newspapers for some quick cash. Anyway we were walking when we passed this house that my friend swore had a evil entity in the basement. So me, being the joker I was, thought it would be funny if I stepped onto the porch and looked through the window and act like I saw something. So I did just that. To my amusement it worked, but what I saw next wasn't part of the joke.
This woman with long black hair covering her face wearing what looked like to me a white night gown was standing in the window I just looked in! Needless to say, this disturbed the hell out of me. So I ran and jumped off the side of the porch. After I hit the ground, I just so happened to look behind me and saw this mans face that looked like it was burnt badly peeking around the corner at me! After I saw that, I ran. We came back a few hours later after I regained my composure but she was gone. My friends saw it but if asked about it, they deny it.
I don't know if what I saw was actually was "evil" or if it was just some spirits that wanted to turn the tables on a young jokester. Either way, it disturbed me deeply but at the same time made me more curious about the supernatural. If I experience anything else I'll post it here. Thanks for reading!
