i freaked out a few months ago after i read the regulators for like the umpteenth time, i woke up in the middle of the night and started shrieking my head off cause there was what appeared to be a cluster of floating red dots across the room, turns out it was the heater in my fish tank, but still it scared the crap outta me, the regulators (n desperation 2 a lesser extent in my opinion) is like the excorcist on steroids
