Two Sentence Horror Stories About Space
Space horror replaces the dark forest with vacuum, distance and nowhere to run. These original stories use airlocks, radio silence, wrong stars and cosmic scale rather than simple alien jump scares.
Every story here follows the same rule: exactly two sentences. The first sentence establishes a stable reality; the second sentence changes what the first one meant.
