I had a similar experience. I was around ten years old, and experiencing sleep walking mixed with nightmares once every few weeks. My bedroom was on the attic floor, as was my brothers room and a play area by the stair case. There was a gray and white “queen of solar mathematics” who was like a ghost, following me. She would not let me go back to sleep or leave me alone unless I could trace the floor plan of the attic into squares. I had to walk on the perimeters of the squares only, and if I messed up I had to start over from the corner. It felt like forever, I was more and more tired and making mistakes. I could see my body from above at the same time as being in it, like it was a video game. Eventually I think I collapsed and woke up at a random spot early in the morning. My brother asked me what the hell I was doing.
