Yes,
Energy transforms and whether you project that energy in dark or light way is how it will perceive, I am not saying that demons or dark energies are merely in our minds, because the collective energy of our world has enough negative to keep the process of darkness active and the universe ââ¬Ënaturallyââ¬â¢ offers energy of dark and light.
When dark energy has enough faith it is able to manifest, and this is most commonly done by attachment to a living form- a human.
All religions portray a ââ¬Ëdemonââ¬â¢ for fear, and as much as religious followers believe in their god of choice, they equally believe in the wrath of their devil/demon/fallen angel.
