No one actually know what demons look like. Some say they're red with a tail, pitchfork, and horns, but you would have to go to hell to figure out what they actually and truly look like. I can tell you this though, demons used to be angels. (yeah i know everyone knows that, but...)
In my experience its always been a dark shadow. no form to it . i used to be followed by a man but i knew it wasnt a regular spirit because i only saw an outline but it was all dark and it slowly started getting closer to me. it had a very dark vibe and in my dreams it would take the form of a little boy. Demons disguise themselves but they are mostly an all dark shadow
Look at pictures from the game dante's inferno they came pretty close, demons generally look like mixter of man and animals, angels dont look like humans either and since demons are fallen angels u can look up passages from the bible
Who knows? There are many forms of demons, I think. Like in some myth, you shouldn't go in the forest alone (in thailand or Tibet or something like that) because these red demons( I think it's red) willl attack you with abow and arrow or something, or the pitchfork/horn thing.... Honestly, I think that demons look more like the minotaur (like from the lightning thief, if you saw it). Although that's more of a theory.... I don't actually research demons themselves. I jus hear about them.
I have demons bothering me now. They come as shadows to me. Sometimes the shadows have horns, feather hat, pointy beard, pointy nose. I feel them touch me. Sometimes my necklace will move. They hurt my foot twice, when I run from them. The calmer and cool I am, the more that wont come. They like to terrorize people. They get a kick out of it. Sometimes the shadow will smile, like there laughing. Just don't knock on the Devils door and u won't have to worry about them.
Demons can come in different ways such as disguises. and by disguises I mean they could come into the world by looking like a normal person or even just come as a ghost like figure and I can tell you that even though it may not seem like it they are everywhere.
The beings we refer to as 'demons' are once angels banished from heaven. As such they are spirit beings with no specific physical form tho, like heavenly angels, can take earthly forms when necessary as they wish.
Who really cares about their appearance. You'll know if you've encountered one. Your whole being will feel heavy by the weight of evil encompassing it. It's best not to delve into the demonic realm & you'll be safe.
Well, Demon's are really all different. I've seen one. But, it was just a black figure running across my floor! Which scared me enough. My dad says theirs a lady demon in our house. One time he was praying and she walked across his path. Scary huh?
