My sibling might be a therian.
OKay so heres the story, My parent was taking my sibling to school, i was in the front seat and talking to my parent. I then mention that "does anyone else feel like they have extra limbs? Like wings or tails?" My parent then said, "What? You're crazy, no one ever feels stuff like that. (pauses and thinks about it) well, if u feel wings that means your an angel and that my aunts are watching over you." i then said "then why dont u experience wings?" (that was kinda rude of me tbh)
but anyway, then my sibling said "sometimes i feel wings" and i asked "do you identify as an animal?" and they said "i sometimes feel like a winged fennec fox, or yeah" and that kind of freaked me out.. because im also a winged fox. They never really answered if they identified as an animal though, so im going to just say that they experience phantom shifts. (Shifts dont mean ur alterhuman, unless u want them to be, like otherlink or somthing, ofc.)
Theyre not familiar with alterhumans or labels within the community, though i did explain therianthropy to them. I feel like they need time to figure it out on their own, and plus they could develop out of therianthropy since they are young. Im not going to force a label on someone that doesnt know or want to be one.
