Thank you for ruining my evening ! :C

For me the "Dining Room" is the scariest.
As for the Walrus:

The video is actually footage of a cross-dresser named Johnnie Baima, also known as Sandie Crisp and Goddess Bunny, taken from a 1998 documentary. It is said Baima has polio and is permanently disfigured due to a botched surgery in which a steel rod was placed in his back.

It's not the product of a cult nor is it cursed. It is a video that runs an audio track of the song "Itsy Bitsy Spider" sped up and then ran backwards. It creates various disruptive visual images with swirling colors and footage from the Goddess Bunny documentary. Basically the short clip plays on the mind, disorients the mind with discordant sound and unusual visual designs and plays on our fear of those who are different and our stereotyped images of people with disabilities and ideas of gender and "looks".

However I do not recommend watch it alone in the dark.
