So I’m almost certain I’m kin of a certain character from Undertale (not saying who because spoilers). I have shared memories with someone else who was from my timeline as well as astral limbs, but I keep doubting myself because I came to the realization only a few months after I finished the game, and I didn’t meditate or anything like that. Would you say this is still fictionkin, or is it something else?

Sometimes realizations come slowly. And you certainly don’t HAVE to mediate to know you are kin- that’s just something I advise when someone is trying to find out who you are. 

Sometimes when you awaken, its a brutal process that hits you over the head the instant you see the material. Sometimes, its not. Sometimes it takes a while before it sets in what you’re seeing is you. I’ve been on the end of both kinds, so, its definitely not just you. I would say that this is no reason you couldn’t be fictionkin.
