Got up twice last night

So Sissy got up around 1am and was sleep walking. I just gently put my hand on her shoulder and turned her around and got her back to her room.

She then got up at 3am. This time I just followed her to see what she might do. She walked into the living room and just kinda stopped. I was about to lead her back to her room but she started walking again. She walked to the couch and laid down. She didn't move for a few minutes so I got a blanket and covered her up. I sat in the recliner next to her and waiting to see if she got up again.

She woke up this morning very confused. She didn't remember getting up at all.
