What the scariest dream you ever had

I had re-occuring dreams of being visited by what eastern European refer as the "old hag"

I woke up and I was paralyzed and I wasn't able to cry out no matter how hard I tried , and the screams was almost completely internal and only a wimper could be heard ...... They were so bad and frequent at one point I became afraid to sleep , until exhaustion took over ,,, I had these up until the age of 30, when I eventually read some piece of literature that described someones experience of being visited by the old hag ,,, and I immediately recognized that thats what was happening to me , and it completely dispelled it ...
