Between the ages of 4 - 7 I would see a demon that took the form of a massive wolf. It's eyes had a deathly pale glow, and when it opened its mouth I heard horrific screams. Sometimes it would say shit in some weird language that I didn't understand and the language didn't sound anything worldly in any way. When I was 12 I saw it in a dream and killed it. Haven't seen it since then, but it still scares the shit out of me when I think about it.
Even though I haven't seen it in years, my thoughts have become darker since then.
Is it truly gone /christ/ or is it somewhere out there still?
