I'm a cambi therian, which means my therian identity is fluid between other heart and therian. For example, today I feel more connected to peacock spiders (other heart), and a couple days ago I felt like peacock spiders are me (therian). It changes a lot, tbh, and it's not that well known. Fiction heart is like other heart but with fictional characters. I just found this out a couple days ago, and I feel connected to Gangle and Bubble from TADC. It's pretty easy to understand, tbh. I never really tell anyone, but I'm an alicorn otherkin >.< I get wing phantom shifts and horn shifts too. I don't really like talking about it. Idk why, but otherkin are like therian but with fictional animals. It feels good to to be open about this!
