I'm thinking of লেখা a creepypasta?

Hi, i want to write a creepypasta, but im not sure on which category to go with, i have two specific ones, which would make a better story though? I'll have a small বিবরণ sort of for each one.

- Beings / Entities (ghosts sort of )
OR
- Madness / Dreams (Insane, dream monsters. )
