Not to be too much of an old man, but I do feel like the total digitalization of the world has sucked a lot of the scary mystery out of these things. Analog TV was spooky stuff! Local stations and public access led to some wild people getting on air. Depending on where you lived and how good your signals were, you could also pick up over the air pirate broadcasts or the ghostly partial images of the premium cable channels your parents couldn't afford. Was that a nipple you just saw... or a ghost?!

Eh my childhood anxiety created some terrible phobias and imaginations of horrible stuff. Nothing gorey, but stuff like bananas had flesh eating bacteria, the mirror version of me was trying to kill me, and there were small people living in my walls and eyes that I need to stay quiet or they would hear me. Completely nonsensical, but it was my child-brain trying to justify my intense anxiety.

Compare with genuinely creative what-the-fuckery, like nightmares of a wild adult Teletubby with a full rack of antlers.
