what you are describing, happened to me the other day. it freaked me out. i was in bed, and just couldn't move. my husband says it was like i was dead. there are times, when i do something, especially when overly tired, that i don't remember doing. my husband says i made a bowl of chili i don't remember making. he brought home burger king i don't remember eating, then i asked for more food, because i thought i hadn't eaten. he came to bed one night, and i am standing in the middle of the bedroom, telling him that he just asked me to do something, when he hadn't. he will come to bed, and there i'll be, sitting up, rocking, sleeping, with my eyes wide open. he will carry on conversations with me that i don't remember having.
what the heck is happening to me????? i feel stupid, and i used to say that i was having one of my "i feel stupid today days", now, they happen every day!
good luck, and god bless
