SCP Foundation

I came up with three SCP ideas. One is a book about the readers life up until their death and if you rip out a page you die at that point. Another is a creature that lives in mirrors and takes the place of people's reflections. If you look at it for too long then it will take control of your body. When it is in a body though it will be forced into any mirror it looks at. The final SCP is a large arachnid that impales people with its legs and takes one bone from their body. Once it has a complete skeleton the skeleton will come alive and start killing people. I would love to know if they sound similar to any SCP's you've read.

Well, here it comes:

• The first idea is odd and uninteresting. Its a thing that does a thing, nothing more, nothing less. Second, why do we die when we remove the paper piece?
• The second idea is.. I dont really know. Its a thing that possesses people and make them be part of the mirror. I dont think is lethal, but I also dont think is interesting.
• The last idea is.. terrible. First, its an arachnid that kills you with its legs. It's not even anomalous. Even though, this is just a TTKU¹, with nothing interesting about it. Second, we already have a lot, like, too many monster skips, and rarely some of them succeed.
