Sometimes when I am falling asleep I have this weird feeling like I'm spinning or falling, even though I'm just laying in my bed. It's almost like being on a roller coaster ride. I know that if I open my eyes, the feeling will disappear, and sometimes it goes away before I fall asleep. If I can fall asleep during it, though, it usually leads to lucid dreaming.

So does this happen to anyone else? Does this weird phenomenon have a name? Is it directly related to lucid dreaming? I can't find any information about it anywhere online.
