Last night my events per hour *doubled* but I feel better?

Started CPAP last week. Woke up last night and couldn’t fall back asleep (usually I can’t get myself to stay out of bed). I feel more alert and I can remember my dreams, which also felt maybe more coherent than usual. But my average events per hour last week was 15.75, while last night’s was 32.3. I use a P10. Anyone know how to interpret this?
