The old hag is an experience, i've noticed i get it only when sleeping on my back, so i don't let myself sleep on my back anymore. It's weird because i didn't even know what it was till about 2 months ago then it started happening nearly every night for a month now i haven't had it for a week thank god! Don't want it again either, Me too don, i try to sleep as little as possible and mostly i wait up till about 5 Am before i sleep so it's getting light i've never had it when it starts getting light for some reason, always has to be pitch black so it makes it even worse, but i had a little light when i saw the hag, so the dark may be hiding whats actually there. You guys know how long you have it for if you haven't been woken up? Mines usually about 3-5 minutes but i think i got so scared the first time it was only about 1 minute.
