It’s not paranoia if they are out to get you.
You become a master of seeing shadow monsters in your peripheral vision.
Those fuckers aren't sneaking up on you.
When alone at night you ignore the weird noises, potential burglars be damned.
Hahaha, nice try monsters! Not investigating that. Nope. No.
You are pretty sure that cold spot is the vent but just in case you avoid it.
Or at least cover up with an anti-ghost blanket. Everyone knows ghosts hate fleece.
Then berate your cat for staring at that spot unblinking for hours.
Stop it Fluffy.
