Nightmare's Aura And How It Works In My Interpretation

Nightmare's aura and how it works in my interpretation

One side of Night's aura is the one that is “default” to him, where he spreads negative emotions making it uneasy for others to be near him for long periods of time due to discomfort they feel being with him. It never affected Dream as his own aura canceled Nightmare's. It's not influenced by Nightmare's emotions, but training helped him be able to lower Its power or enhance it, whenever he wants to. At Its strongest it can implement unexplainable fear and paralyze the opponent from terror they can't understand. He of course can't use it frequently because that would be overpowered.

The other side of his aura he learned by himself is where it calms others down, works both ways in intensity just like the “fear aura” ranging from pleasant calmness to a state of chill when one doesn't care much about anything. Part of this is also making the person sleepy or sluggish which can also be used in battle. For example, a person fighting Nightmare suddenly gets very tired, their legs tremble and their eyes can't stay open for long, slowly losing consciousness.

With both auras, “spells” can be cast, it just means a specific aura is channeled onto one person to affect them specifically. There are certain situations and people that his spells don’t work on, for example Ink and Dream. Dream can only be affected when the spell is very strong and it doesn’t work at all on Ink since it’s mostly emotion based.

Of course every drastic change to Nightmare's aura or casting channeled spells makes him weaker and when he wants to use a strong spell he has to estimate how long he can keep it up so he doesn't tire himself out.
