Nightmare

(Inspired by the song 'Nightmare' by Set It Off)

This quirk gives the user the ability to put people into hallucinations or sleep likes states filled with nightmares. These nightmares could be anything from their deepest fears or demons and monsters the user has created. 

Drawbacks;

When the quirk gets overused, the user falls into a coma-like state filled with their fears, demons, and monsters; for how long depends on the over-usage.

Side effects;

Insomnia

Nightmares

Sleep paralysis
