Depth Psychology: Dreaming about demons usually refers to feelings you are denying, but that have, nevertheless, taken hold of you. See Aggression, Disgust, Envy. Frequent dreams about demons are warnings: make an appointment with a psychotherapist in order to avoid future emotional conflict and/or crises. See Devil, Monsters, Mystical Creatures.
Although the word ‘demon’ originally came from the greek word for ‘deity’, for many hundreds of years it was taken simply to mean spirit. In the modern day it is taken to be an evil spirit, one at odds with god, and has this meaning in dreams.
Were you participating or watching? What were your feelings during the dream? Who demonstrated for what? And the most important question that you have to ask yourself is: What would I be demanding or wishing for.7 What purpose motivates me.7
