[...] A very glib guy on the television said some people liken it to being underwater, under a body of water that has no surface, at least for you, so that no matter what direction you go, there will only be more water, no fresh air and freedom of movement, just restriction and suffocation, and no light. (I don't know how apt It is to say it's like being underwater, but maybe imagine the moment in which you realize, at which It hits you that there is no surface for you, that you're just going to drown in there no matter which way you swim; imagine how you'd feel at that exact moment, like Descartes at the start of his second thing, then imagine that feeling in all its really delightful choking intensity spread out over hours, days, months ... that would maybe be more apt.)
