Draco, they have all given you their opinion, it seems you just want someone to say what you wish to hear. You can believe what you want, but there is no reason to suggest any of those creatures exist.
aliens, that's a load. [yes, i believe in werewolves and dragons, but not little green men. maybe creatures on a distant planet, but not intergalactic visitors.]
faeries i've seen one, sprites and those tye are just spirits of nature. i wish there was werewolves, i love werewolves and their myths. if you want to see werewolves and dragons and the like, practice astral projection, then you shall see them. word to the wise, as someone who has met dragons, be respectful and bring an offering, i've only visited there den three times, once to ask for them to guide me in magic, the second time for help after not practicing for a long time [and they attacked me, i wasn't hurt in the physical plain, but my astral self was] and the third to apologize and to try harder in my studies, which i have yet to fail them.
my point [which i am sure you will argue] you cannot physically see them like in How to Train your Dragon, if that's what you're hoping for. only in other plains of existence can you, and even then i advice not trying to ride one, unless you have befriended them and even then i'm not sure.
I'm kinda on the fence with the who werewolf thing. Common sense tells me that it doesn't exist physically, but isn't the philosophy of magic to, at least to an extent, look past what is held true to people and see things for yourself. Also there's been some interesting reports in history, one such report called the beast of bray road, which I found particularly interesting, doesn't seem like it'd be impossible. I'm a very realistic man and at times somewhat of a skeptic but there has been countless sightings in history of werewolfs from the middle ages all the way to current time. I don't think all the sightings might have been valid but when you look into some of the reports you can't help but wonder why countless amounts of people for hundreds of years have claimed to seem this creature we call a werewolf and we simply discredit them as crazy or living in a fantasy world. Who knows we may just be dead wrong.
