Possible name for the demon? [I Believe In the Paranormal]

I've always called it "Plague" because that's what it does, it plagues me. But I just got a pendulum recently and asked it what the demon's name was and it spelled out "Adir". I looked it up, turns out it is an actual name and it means "mighty one" or "strong/powerful".

I'm not sure what to do with this information. Maybe next time I have a dream with it in it I'll use this name and see what happens.
