Nightmare Manipulation is a variation of dream manipulation and is the ability to enter and manipulate the nightmares of oneself and others. The manipulation can be either good or bad and can include modifying, suppressing, fabricating, influencing, manifesting, sensing, and observing dreams and nightmares. The most common use of this power is to produce and modify dreams or create nightmares. The power, if to strong, does have the ability to harm the sleeping victim and at times kill the victim. The death of the victim can occur due to intense fear and/or shock. Nightmare Manipulation is the main power of Moras since they feed off of the fear from nightmares.
