Horror Writing Prompts

Questions writers ask

What makes a good horror prompt?

An ordinary situation with one specific wrong detail, and a rule or constraint the character must obey. Dread builds from the gap between normal and not-quite-normal.

How long should a horror short story be?

Many effective horror stories are very short: flash pieces under 1,000 words can land a single chilling image. Longer pieces need escalating stakes.
