I would bet this is an oh overly active survival instinct. I feel like people describe this if I’m awoken by an unknown noise in the house. Often i don’t even know what awoke me, but I usually feel a mixture of vivid paranoia coming on mixed with the calm feeling the game of archival is on. I call it the silent killer mode and i imagine that’s how cats feel on a hunt. Usually goes away after listening for a few minutes and trying to chill. Sometimes I have to check the house to make it go away.
There is a variation since i have kids that feels like its too silent in the house and something is terribly wrong with one of the kids. I have to check all three are breathing normally before it goes away.
This doesn’t happen on the person, only in the wall. The lightning on the back of his head is good, so this is a shader issue probably
