I love long answers when they say a lot.
Now it doesn't look very scary. It's very generic, but I think we'd all think "monster" if we saw it. Albeit childish. Short, stocky, furry, big eyes, sharp teeth, maybe horns.
I love this. This image of a monster that's so stereotypical and yet not that scary. Maybe even cute, if you emphasize the 'childishness'. Makes me think about the so many not-scary monsters that exist in every culture.
To me I can best describe it as my depression that I've dealt with most of my life. It would be the thing that most has attacked my life and changed it from what I perceived as "should be" into a sort of horror version of what "should be."
Now, this one... not stereotypical at all. Shapeless, yet really scary.
To me a monster, I guess, is that which wrenches a thing or situation into the terrible. It starts off as unknown and then it arrives to shock.
Very interesting description. Thank you for sharing!
