When the Nixie stays silent

I currently try not to push too much when I paint and a new Nixie emerges.
Usually, I start with the background and then I see a face. While I paint her, she speaks to me. Don't think I'm crazy (or maybe I am and just don't really care) but my Nixies tell me their name and their story so I can then share them with the world.

I thought something was off with the Nixie above.
I was SO frustrated because I could not point out what was wrong with her. I changed the background, tried to listen closer. Tried to see if it was something with the Nixie («Is she too weird ?»). None of this was shifting my feeling about the painting.
Then, i realized that i did not have her name nor her story. Nothing. Nada. Niente.
The silence I was facing was killing me. It never happened before. I faced the «I don't know what color to chose. I don't know what her hair should look like.» etc. but never a one-way relationship with my painting.

So what do I do now ? Fight ? No... this is not the best option, in my opinion.
So I think that maybe just go with her flow ? I know this is happening for a (good) reason. Is she a reflection of my own moments of silence ? And I love that while writing all this her name just popped in my mind... Muette (which could be translated with tongue-tied or mute or even silenced).

And maybe that her story simply has to remain her secret for now..?
