Otherkin are people who believe that part of them is not human inside. They say that, inside themselves, they feel more like another animal than a human. That other animal can be, for example, a wolf, a dragon or an alien. Some otherkin say that they are vampires and are usually acting like them, for example by drinking blood.
Otherkin may also say they feel a special connection to other natural elements, for example minerals, the likes of fire, water, and wind, or plants.
