Creepy

Call me crazy but I'm a huge believer in demonology and supernatural events and so on and right now I swear there's like a ghost or something after me. So the other day, there was a cat on my porch and it was just sitting there so i decided to go see if it was ok. It was pretty late so it was dark out. The cat was fine thank the lords but while I was out there, I swear I saw legs running really fast and while I looked that way, I saw a dark shadow on the corner of my eye behind me and when I turned around, there was nothing there. The night after, I couldn't sleep so I decided to go for a walk and there is a street by my house that I usually walk down whenever I need some fresh air or whatever and there are street lights along the way. When I walked past the first street light, it started blinking and it was making a weird sound and I just thought that it was something wrong with the light so I kept walking, when I pass the next street light, the exact same thing happened and already then I got a bit scared. However, I was just hoping that it was a coincidence. But then I pass the third street light and the exact same thing happened a third time. That was when I freaked out and ran home. Tonight, just now, I had nothing to do because there was an hour left until my favorite Swedish tv show started so I decided to go for a walk, and when I walked down that street again, the first street light did the exact same thing once again. This time however, I didn't plan on staying around for more lights to go all crazy on me so I ran home. Scaryyyyy!!! Has anything weird like this ever happened to you? Share your story!
