A different shape

Waking at four again. Not anxious, just awake, lying there listening to the boiler.

Vivid dreams, every night, the sort you have to sit up and shake off. Two other people in circle have the same and none of us can find anything written about it.

Repeat study came back and the apnoea is much reduced. Ten years of that mask.

The sleep has changed shape rather than improved. Different, not better, and I cannot yet tell whether I mind.

Checked twice.
