So we have 500 hours of video horror, what about spooky websites? Here's a couple off the top of my head:
Ted's Caving Page, epic journal from the early early days of the internets, I think I first read it in like 2004 but still very memorable.

Interactive Bosch painting Garden of Earthly Delights. Amazing depiction of hell with great sound effects and narration.
