Do you ever bounce your head to lucid dream?

I have a friend that bounces her head to sleep. It was hard for her to sleep otherwise. She had lucid dreams every night. She wasn’t even aware of what lucid dreaming was, she would always just talk about how she had full control of her dreams and thought that it was common. She recently stopped bouncing to go to sleep a couple years ago and that’s around when her lucid dreams stopped. Do you think that was a contributing factor. Had anyone ever bounced their head to go to sleep and experienced lucid dreaming?
