Monsters in the sewers! Is it real? I wish but this looks like a video of somone’s body getting examined with a tiny medical camera. No aliens here! Move along! Thanks to my friend Charles for this!
UPDATE: Dr. Timothy Wood believes it’s a video of some type of worms. The camera movement and the very organic nature of the intestine-like walls lead me to believe it looks more like a medical procedure. But I’m no doctor!
