In my dream, Satan was sitting across from a catholic priest at a wooden table. They were both casually drinking coffee. Satan was asking the priest about exorcisms. How they worked, what was needed, etc…
Satan wanted to get an exorcism because he wanted to go back to being just plain evil. Apparently, after several millennium of being with his thoughts, Satan had some personal growth. He had a reawakened a seed of his own innate goodness and humility and with that realization he knew he was lost without the knowledge that God might someday forgive him. He thought a reverse exorcism might expel the goodness and take the awareness away.
Weird dream… really interesting concepts.
