This is something that happened to me back in 10th grade. I couldn't sleep and I was feeling restless so I decided to take a walk along the greenway near my house. Most people would have reservations about walking through the woods alone in the dead of night, but it was a safe neighborhood and I knew the greenway like the back of my hand.
No more than five minutes of walking through the woods and I hear a girl singing. I recognize the tune right away, it's Camptown Races. Y'kno, "Camptown ladies sing this song, Doo-da, Doo-da" I look around for the girl, but it's pitch black. Not wanting to suddenly come across her and frighten her I shout out "you have a nice voice!" No reply, she just keeps singing. Weird. I continue walking but the singing isn't getting any further away. Is she following me? Or are we just coincidentally walking the same direction? I make a sharp turn and start walking down another path. The singing follows. Another sharp turn. Again it follows. Okay now I'm 100% sure this bitch is following me. I start trying to pin the location of the voice with no luck. I think she was purposefully changing her volume to prevent me from knowing when I was getting closer or further. Now I'm really starting to get freaked out. I bolt and start sprinting back home. I was running track at the time so I was pretty certain I could ditch her. I get home kick off my shoes and turn on my TV. I'm about ten minutes into an episode of Aqua Teen when I hear a voice that's not coming from the TV. It's a girl's voice singing fucking Camptown Races.
For a brief moment I just sit there in pure terror. This can't be happening. I run outside barefoot and frantically look around. I realize that the voice is coming from above me. She's on the fucking garage roof. I kept a ladder on the side of the garage so I could climb up and smoke weed (my parents thought I was tanning). The ladder was the only way up or down unless you wanted to jump and chance a sprained ankle. This is it. I've got her. I race up the ladder just in time to see a figure in a red hoodie disappear off the side of the roof leading to the backyard. She had jumped. I watched her race across my backyard, completely unphased by the fall and book it over our 6 foot fence like it was no big deal.
I briefly considered chasing after her, but I couldn't in my bare feet. Frankly, I don't know if I wanted to. I don't believe in ghosts and ghouls but I'm still freaked out by the whole thing to this day.
