As a child, for a few years I had a recurring nightmare with multiple false awakenings, sometimes five or six until I would wake up for real.
I would wake up in bed, get up and at a specific point, an overwhelming feeling of impending doom would overcome me. Then at the peak of this emotion, a monster would grab me by my ankles and violently drag me back up the stairs and into bed. I would then wake up and repeat the process.
Sometimes, I was not sure anymore if I landed in reality or if this existence will turn into horror again.
