Feeling—and this is a weird hybrid not-quite-physical but not-quite-mental sensation in that it’s “in” my head but “feels” like it’s the body—as if I have another body maybe a centimeter beneath my skin that wants to stretch all its muscles beyond what my skin permits. I don’t mean that I literally believe there is another body inside my body; I’m not having some sort of break here. It’s just the closest I can come to describing this.
