Mysterious entities

"Shut up. Don't even breathe."

- Sam, telling the Corpse Disposal Team 6 to not make a sound around an entity

Mysterious entities are otherworldly creatures – presented as hand prints to the human eye and sometimes as floating, humanoid wisps – that have somehow "stranded" into our world. They can sense someone by sound, as the trailers show characters often covering their nose and mouth while in their presence.
