Wow, is that accellog from actual sleeping or did you play football while recording? Sorry for the exaggeration, but I have attached the plot of your log, there is no dormant phase to see.
You can compare it with the middle graph in https://ubicomp.eti.uni-siegen.de/home/datasets/ichi14/index.html.en how it should look like.
So either the in your watch has some jitter or your arm. Maybe you can
1) record some acceleration data while the watch is on the desk, not moving
2) have someone to watch you while you sleep (or use a camera, you don't need to show us the movie), to check if your arm really moves that much.
If it is your arm you might want to get some medical advice. I don't know if it is bad, but it does not look normal to me.
