Yes, that's scary

Here's one great thing about writing a horror story: you can make anything scary.

Chucky was a doll. The fog is a deadly entity in one book. Characters of every shape and size can suddenly have murderous urges when given the right motivation—or even better no logical motivation at all.

You can make anything scary if you put the right context around it.

So next time you're low on inspiration, just look around you and think about what you see in your surroundings that you would most hate to have attack you. Once you find that, get to writing and make it scary to the rest of the world.
