Also people who really believed this wouldn't be celebrating Halloween in the first place (and the description on Youtube is pretty obviously fake). But it's a worthy effort.
This reminds me of when I was eight years old and my mom was fucked up on meth, and it was night time and there was a auto mechanic shop across the street, and the bulb that lit the sign was low and would flicker every so many seconds. She swore that it was someone sending her Morse code in the middle of the night. Also, power surges = demons.
