what beings are real?

Merlin is a fictional character in the Arthurian legends, not a real person.

In the legends he was the son of a human mother and a God of the Earth. But again, this is legend, not fact.

i believe in mermaids, and faeries especially, but not everything. you have to remember, some people drink human blood- and call themselves vampires :/
also some people dont believe in demons, devils, angels (which may or may not just be a list of the same thing repeqted so far 3x) or spirits, ghosts

and the big one- witches and witchcraft.
so whos to say they cant be real? in the right conditions anything is possible, and we live in an infinite universe! (theory)
so why not?

What you believe doesn't change whether something is real or fake no matter what. However someone else has no power either. No one has yet to prove the existence of such things nor been able to prove them false. Saying that someone is living in a fantasy world for believing in these things is just as ignorant as confirming their belief without enough evidence to do so.

I see :(

I too like anime.well, the main reason to like it was that in most of the anime shows such as demon summoning,specific demon name,witchcraft,characters are found to be real but the story they are put in is fake,of course.for e.g. sebastian michales in black butler,all demon characters in nura the rise of the yokai clan,witchcraft in rental magica,etc are all real.

Also an anime named BEELZEBUB,how can i forget it.

I know this is completely off topic but I need someone to guide me through this im very new but I strongly believe in all of it but im unsure of things and I want to be able to learn properly.

Windigo physchosis is a mental diease where people believed they were turning into a flesh eating being, craving human flesh. Though this illness itself at one time was believed to be a myth, we are now seeing examples of it. Here in Florida a while back, a man killed, and was eating his victim when police found him. The police shot him several times while he continued to eat, unbothered by the pain he must have felt. Finally the officer was forced to shoot him in the head. Later it was discovered that the man had a history of mental illness, and was using bath salts ( a drug that was legal at the time ). The combination of the drug, and mental illness may have triggered a state of windigo phsychosis.

It is not insulting to say that somebody "lives in a fantasy world". Fantasy is just another word for imagination. All children live in a fantasy world. Look at some of the great authors of "fantasy"; Lewis Carroll, Terry Pratchet.
Adults who "live in a fantasy world", see many things with "wonder!". They remain childlike, as Hans Christian Anderson.
(Childlike! Not Childish!)

Actually vampires and werewolves do exist in this world. They blend into society and so no one would suspect them to live here. Same with shifters and other beings that aren't totally human. Its odd and sometimes hard knowing you're different than others but its important to not stand out.
