yes i can definitely relate Claritytoo, i did not know they are body memories, they just felt weird, like i am not incontrol, but could control it if i tried, was not remembering anything visually but was totally concious of what i was diong yet did not want to stop it as it felt so right. I have had loads of these episodes. i usually feel exhausted , numb but very calm afterwards

my body definitely has it's own mind, along with legs that will not move unless my hands move them , no control over any bodily functions down below and my inability to sit up unsupported, my arms and back spasm every morning for over an hour on waking up and everytime i get tired or wake up in the night. all i can do is try not to fall off the bed and wait till it passes
