In the past year or so, three internet mysteries popped up that really got my attention. They may seem very different, but trust me, they're connected.  The first one is about a girl who found a door in the basement of her AirBnB. She opened it and inside was an abandoned shopping mall.  

The second story is about Javier aka Unico Sobreviviente, who woke up in a hospital in the year 2027, in an alternate universe. In his version of the future -- everyone on earth has vanished. He's the only one left, and he has video to prove it.  

The third mystery is known as the Backdoors. A reality adjacent to ours that, if the conditions are just right, you can accidentally slip into. Then you find yourself lost in an endless maze of dingy carpet, fluorescent light, and yellow wallpaper.   

And around every corner--
