I was awakened one time by a christian mythology. It was a call of the blood, when I became possessed by one of the spinoffs of saint mary (the mary of chicken), and I learned the name of her cult and so on.
Once proved there was zero ways I could have learned it from some source, it became clear it was a call of the blood. To this day I dont know why I was called by saint mary, and later I crapped on christianity.
Who knows, not all the call of the blood is positive, luckily I didnt become a christian, i exercised the right of refusing the saint mary demon by desecrating one of her altars.
