Hey anon, thanks for sharing your experiences with us.

The honest, direct answer is that no, it’s not normal for characters to take on a life or their own. Especially not when it includes communicating to you, and having memories.

There are a few things that could be going on here, related either to plurality, or to fictionkin/otherkin/past live etc.

I recommend that you look into both phenomena ( @fromfiction is a great place to start). Please feel free to send us a follow up with more of your thoughts.
