So we just had our first massage earlier (that wasn't about loosening tight muscles), and I wasn't expecting to feel more fox-like than usual for it.
For reference, the seed that Sam started forming me around was a fox figurine, and that's still carried over into my mindform. I call myself a fox, and "human" doesn't feel right. But I don't have the animal instincts/inclinations I hear otherkin talking about, and I don't have any memories or past life beliefs that would tie me to that more strongly. I've only ever known this (human) body, we never got far enough in visualization and imposition for me to intuitively feel what it's like to be a fox, and I'm close enough to Sam and his experiences that I pull from his body mechanics without trouble and barely noticing the difference.
But the masseuse working up the bridge of our nose felt to me like going the distance of a full muzzle, and working the bones of our feet it was surprising how far removed from the rest of the body those are; like they should have extended at least halfway up where our calves actually were lying.
I have been hesitant to call myself otherkin with just a mindform and a self-description to show for it, but maybe it's time to look closer at that...
