Ok, so the basic story (as far as I remember -- I'm sure one can
What irks me about it is that the "hound" looks like a hound and is hounding him. If it was called a "hound", looked canine, but didn't track him? Wouldn't be so bad. If it was called a "hound", had a thing for tracking, but didn't look canine? Also wouldn't be so bad. But the combo just kind of gets under my skin.
What I'd prefer is if the visions were dreams and involved what appeared to be an origami orchid made out of smoke that is folding and unfolding in a cascade. The smoke fades in and out, but instead of doing it in swirly random ways, it's doing it in what seems like some obscure mathematical pattern. From this cascading origami smoke orchid (AKA: COSO), the image of a hellhound initially glared at him.
In the subsequent dream visions, the cascading of the COSO has the gist of it gradually expanding, although it sometimes has to contract itself for a few moves to allow for the next phase of expansion. Each dream ends with the hellhound running towards him from the COSO, and later savagely leaping from the COSO.
Blah blah blah, eldritch horrors, things I can not.. nay, must not describe, you know the drill.
But instead of it all being in a diary, we conclude with:
When the hound began to manifest, I realized the image of the mastiff was but my mind attempting to find a symbol to express the entity. The arabesque form I had seen was closer to its true visage, although no more than a looming shadow is the face of an approaching executioner.
Fade to black, roll credits.
