I came across these independently-made cartoons on YouTube earlier this year somehow, and they were creepy, disturbing, and all-around bizarre--which made me save them for Halloween. I haven't done the research on the creator of these cartoons, but based on his YouTube uploads, he specializes in these grotesque animations.
The only thing I can really say to set them up is that they follow a man's psychosis and paranoia. It's hard to tell if some of the things seen are real or in his imagination. Either way, these cartoons are, as the title states, the most disturbing things I've ever posted here at the blog.
