I think for some folks there’s something primal going on, a feeling of being trapped when things are over their faces that they can’t shake. It seems like something deep-seated and unconscious, really hard to get past. I get that way if I can’t freely move my arms and legs while sleeping, but the face has never been so bad.
I wish I knew some advice I could give that would help people struggling but whenever food, sex, or sleep is involved, we’re still weird fleshy worm tubes twitching our way through a hostile world.
