Is there a known demon or ghost named Hannah?

When I was a kid, I had reoccurring encounters with an “imaginary friend” named Hannah or something extremely similar. In one situation, my aunt was driving me and my mom around and my mom heard me choking in the back. I was in the backseat scratching at my throat and they asked what was wrong and started freaking out. It quickly stopped and I had a red handprint around my neck. I told them that Hannah was choking me. My mom had recently brought it up with me and I’ve tried doing research about it but have come up with nothing. I’m just hoping that someone has some type of knowledge about this.
