Your mind is shouting at you "just so you know, here's a preview of the next nightmare: the theme's gonna be dismemberment, why don't you just close your eyes?" and then you're trying your best to move. Only the left foot seems to move - moving very fast actually, but is it really moving in the real world? It's feeling so real, is it severed? Wait, I'm trying to wake up, I must not think in dream logic, I just need to...
Oh, I can move now. Fuck sleep paralysis.
