Looking at crochet patterns

Do you know what I realized today? That there aren't any patterns, for my ideas. I love horror movies, they are all I watch, and I have what I think are interesting or unique ideas for things. I have looked all over the internet and I haven't found patterns for what I am thinking of. I love zombies and I haven't found any kind of patterns except for amigurimi's. Or a knife pattern, or a blood pattern, or anything that is remotely scary. I couldn't even find a fly pattern for my Amityville idea. It's kinda frustrating, in all honesty. I have only been crocheting for 4 years, and I have written two patterns. But what i am wanting is a bit more complicated. Hopefully in time, it will happen.
