Synpath is a tidy name for something you identify with on several levels, which could be a concept that resonates really strongly with you, an animal or mythological creature you feel you act like, or a person or character you share a lot of common behaviors with, among other things. —source

otherhearted is a term that's also similar in nature to a synpath.

to summarize: these are characters i relate to in some form, or in concept of something i relate to; i've grown up around dragons my entire life and used to pretend i was one (phantom limbs, losing time flying in games like spyro, etc), so i still feel a deep connection there.
