Silent Still is the first of two games to focus on the horrors of sleep paralysis.
As someone who's experienced sleep paralysis a few times now, the game does well to capture the feeling of helplessness as your mind manifests malevolent beings in your vicinity.
The genuine horror you feel while darting your eyes around, what should be, the safety of your home is palpable. This should be my sanctuary, so why does it suddenly feel like the worst place in the world?
My one running thought throughout this game? Close your doors and turn the bloody lights off!
