Reincarnation

I was told this story a while ago but I haven’t really told anyone outside my family. When I was younger my favorite animal was elephants. But I didn’t call them elephants I called them Aculars. I couldn’t watch the movie Dumbo because of how they abused them in the circus and I would cry watching it. My parents tried telling me they were called elephants but I got so mad and wouldn’t listen to them because I knew they were called Aculars. My mom went over to her moms house which is my grandma and told her about me calling them Aculars and she was so stunned and started balling and my mom was so confused and asked her what was wrong and he said that Acular is the name of a Nova star and Nova was my grandmas moms name. She then proceeded to tell my mom that when Nova was younger she called elephants Aculars too. I have never met my great grandma she passed 10 years before I was even born so there’s no way I could of heard it from her. What do you think? If not reincarnation then what is it?
