One of the things I hate is (usually amateur stuff on YouTube) in which the person is getting overly scared even when it makes no sense.
Like they'll over act and start hyperventilating at a leaf and saying shit like "Oh my god what is that?!?!?! WHAT IS THAT?!?!" at like...a thud in the distance.
YouTube and Ghost Hunting shows seem to be the worst offender.
Another trope I hate is a horror game one but it's somewhat related; I hate it when the game tells you when to be scared by having a "sanity" effect or by the player character gasp or scream or whatever. Worst is if they have some kind of heartbeat sound effect that plays when you're supposed to be spooked.
But yeah, if a character starts saying shit like "WhAt ThE FuCk WaS ThAt?!" then I just get more annoyed than scared.
There's a comedy script somewhere in here about a ghost realizing far too late that the young professional that just moved into the house its haunting is a lab assistant hungry for grant money whose response to seeing her furniture float is to start fantasizing about the Nobel prize she's about to win.
The moment she realizes the spirit is trapped in the house she immediately starts setting up an exact perimeter of ghost territory and setting it up like a containment area
