How do you sleep?

My relationship with sleep has always been strange. I have been known to sleep solidly for 16 hours straight. My wife recounts strange incidents of being unable to rouse me, "as if you're dead." And yet I can go for extended periods with little or no sleep. I once drove through the night, midnight to 7 in the morning, stopping only once for petrol.

I am visited by the night hag frequently. Scientists call it sleep paralysis. It is unbelievably terrifying.

I have not been to bed before 2am for 4 nights straight now, and I feel great. I am being busy, organised, focussed. Last week I wanted to stay in bed all day. That's not true. Last week I had a need to stay in bed all day. The simplest tasks seemed extraordinarily difficult.

There are echoes here of manic depression. I used to joke about it, but writing about yourself clarifies disparate thoughts, allows connections to be made. I need to think more about this and what it means.
