In England, we know about vampires and draculas. In China and Korea, they have different forms of zombies. In Philippines, we have while lady (ghost lady floating in midair), monster with half bat half woman with waist cut and can fly leaving her half body, tikbalang (half horse half man), capre and agta (a giant black man residing in big trees), sigbin (similar with malay civets but mythical creatures), witch or wizard who can change themselves into an animal they like(mostly dog, cat or pig), dwarves, laughing clown (tambaloslos) and 3rd dimension people who reside in trees, forests or cliffs which they themselves can only see.
You forgot about the 2 most famous "real" myhtical creatures in the Uk. First, the Loch Ness Monster - most likely to be a type of dinosaur that survived the global event. Then there is the Beast of Bodmin, a huge wild cat that eats sheep when no-one is looking.
They must be real, they appear in the Sun newspaper all the time!
Here in India, we share borders with Nepal in north and north-east, along with valleys of Himalayan mountain series. There is a controversy here in those valleys since hundreds of years and that is about a giant living creature named as "Yeti", who is half-human and half-gorilla (or ape), resembles like old ancestral ape-looking species of humans. Local peoples call him "giant ice man" as according to them, he is 10 feet tall and his skin looks like it is covered with a white-fur. What controversies say is true or not but as per their sayings, his footsteps have also been spotted by local peoples, tv channels and some geographists too. What photographs and footsteps say about that special creature is only a mythical controversy or some truth!!, only God knows.
I'm not too aware of any mythical creatures in Pennsylvania, but, on the topic of ghosts, there is the Eastern State Penitentiary in Philadelphia which is supposedly one of the most haunted places in the country.
I don't know if it's mythical, or not, but when I was a kid we lived in France and were going to go fishing in Lozere. One of the neighbors told me a story about the beast of Gevaudan. Supposedly wolflike animals terrorized the region in the 18th century, killing over one hundred people. He said they were werewolves, but from some things I've read they think it was an ancestor of the modern day wolf that had somehow survived extinction over the millenia.
The Beast of Gevaudan was no myth. It was an extremely well documented case; and the eye-witness descriptions do indeed support the theory of a prehistoric wolf species. However, being near impervious to bullets- possibly a higher vibrational rate- the more likely answer to its origins- according to some investigators- is a time or dimension portal opening up vs any breeding population surviving through the vast millennium. The best researched and detailed book on the Beast is by the French author Aimee Pourcher translating from the original reports. King Louis the 15th but a large bounty on its head too by the way.
In india, each state has it's own share of mythology, ghost stories and spoky stories related to the castles of the rulers in past. In my city, there are not much of stories of despairs of ghosts but yeah, there are some rumors mostly and nothing credible as expected. I don't remember much of the stories in this region right now, but will post if i remember something worth sharing.
