Works really well if you’re genuinely paranoid!

Action:write your name on a piece of paper in your own blood and drop it into some oil(sunflower if possible).Then act paranoid for 24 hrs- flinch at loud noises, pretend to suspect everyone of treachery, carry a knife everywhere-that kind of thing.The better you do at this part the better the ritual works.If anyone figures out what you’re doing they can go along with it and the ritual works fine but if they mention it or you mentioned it previously then the ritual fails.
Then stir the oil 3 times counter-clockwise with a banana.At this point the oil can be stored indefinitely.
When you want to use it write your targets name on a piece of paper in his own blood and drop it in the oil.

Effect: the target becomes paranoid for 24 hrs

What you hear:
The banana is completely unnecessary but if you stir it with a gun well………

or alternatively
What you hear:
If you could only figure out the right symbolic action and object for other feelings(banana=paranoia huh???) you could make it so much more useful

Or maybe you hear both of those things…
