As I've mentioned in other posts, I'm otherkin. Specifically, I'm a mythical bird of sorts, though have yet to find more details...
I do have few memories, such as flying and blocking out the sun almost completely (I was pretty big, to put things lightly), and very eagle like. I was almost entirely bird, with some human characteristics, such as human like hands and arms...but I'm not so sure they were always "out". I think more often than not, I was just "bird". I was a "giver" of wisdom, so it seemed.
Granted, if it weren't for these memories, I'd consider it mental. I still am what I was inside.
