Yes you are right,, Demons aren't like in the paintings, coz it's just the imaginative mind of the artist..
I had once encountered a demon,they do shape shift. They can be anything or anyone that they want to be.. You can just know that they are demon on the energy they releases..
They follow people like they are something like a stalker..
They want something on that person and they will not stop until they got it.!
I DO NOT RECOMMEND TO EVERYONE!
DO NOT MESS WITH DEMONS..
