For me it was the Hag I grew up hearing stories about, or the Boo Hag, or the Old Hag that would ride your back. I was told as a child, even to this day, it was a spirit that would ride your dreams and steal your life force, as you slept. And the telltale sign was when you would feel a heavyweight pressed down on you and you were unmovable, and you can’t move. And I’ve had quite a few encounters with the Hag. So yeah, but that’s something that I was always told as a child, and you kind of just have to say, “I rebuke you in the name of Jesus,” and it usually leaves.
