In tulpamancy communities, people sometimes discuss about how they get unintentional tulpas from their own creations and the struggles that come from it (the typical struggles of being from a source, including when your life is written on a page).
I like to see my characters as friends and sometimes form a bond with them where we converse or they can "visit". They never deviate to become different (something tulpas often attest to when from a source), but I do learn more about them. We lurk in the tulpa community, so that's why I brought it up a lot in this, haha.

Also, I do have a question, if it's okay (if not feel free to ignore!). Do you guys have any information about soulbonding from the "artist talking to character" part? We knew about soulbonding in the spiritual sense from tumblr posts and old websites, but could rarely find any information or community from the other side of the spectrum, aside one older website that talked about it. I'm not sure if there's anything more to that side of the community, but it can't help asking.

Thank you for sharing you& experiences in fictivity!
