I was walking on a forest road when the closest streetlight started to flicker and got black just when I passed it. It would have been okay if it wasnt for the other 10+ streetlights doing exactly the same, just when I passed them too.
I don't know if it's the scariest, but at least it felt pretty paranormal :D
Beware, I live!
I am Sinistar!
Beware, coward!
I hunger!
Roaaaaaaaaaar!
