SCP-966

Laconic Containment Procedures
Keep an eye out for anyone who has died violently relating to sleep deprivation. Keep the four we have now in a lead lined cell with infrared cameras. Feed them 20kg of meat each month. If the one female gives birth, study and then kill the baby.

Laconic Description
Tall hairless and weak humanoid creatures that feast on animals, particularly humans. They are completely invisible to the naked eye and can only be seen at wavelengths between 700 nm to 900 nm (infrared). They emit a previously unknown wave that makes people unable to enter REM sleep. When their target is rendered incapacitated by the lack of sleep, they will eat the target. There are many SCP-966 that appear all across the world.
