So this might sound dumb but around the first month I was home I like so many others continue to try and move my lower body parts. Tell if any body els try this or if it was a accident. I was laying in the bed drinking water when I was trying to squeeze my butt cheeks Lmao when I happen to look down and seen the water in the bottle moving so naturally I though I may have moved it wit my arm by accident. So I waited till it stopped and squeezed my Ass aging and the water move. Lol was and still happy about that .I'm guessing that's what they mean when they say u may have move ment but its so small u can't see it but u can feel it b
