I remember a long time ago, I think I this lucid dream that i was just constantly free falling. It lasted for a few minutes and suddenly I just hit the ground and I woke up. When I woke up it felt like I was bouncing on the bed, cause there was still some movement. It happened when I was younger, say 8 years old?

Has this happned to anyone else? Like you dream you are doing something, and when you wake your doing that thing, or something related to it? Kinda like sleep walking or something.
