Eerie Horror Feature Film Teaser Edit

I have a finished horror feature and now need a 30–45 second teaser that drips with unease. The cut has to feel unmistakably eerie rather than outright frantic, so I’m picturing slow-burn pacing, uncomfortable negative space, and an ambient score that seeps under the skin...
