One complaint, four different problems

People say I do not sleep, and they mean four completely different things.

Short sleep is not getting enough hours in the first place, usually because the window between the last thing at night and the first thing in the morning is simply too narrow.

Broken sleep is getting into bed fine and then being awake at two, or at three, sometimes for an hour, sometimes for the rest of it.

Late sleep is lying there wide awake until three or four and then sleeping perfectly well once it finally comes.

Unrefreshing sleep is the strange one. Eight hours, on paper, and you wake as though you have not slept at all.
