Could this be a sign of not having enough physical activity during the day? What other reasons would this happen?

It seems to be one of my only boundaries keeping me from getting another LD.
That sounds similar to me, but I kind of 'blank out' then suddenly realise I have been lying still for ages, and have no sense of how long has passed. However, because I can still move and nothing happens, I don't consider it SP. is it still be SP if you can move?
