Why do I irationally think I might be transgender?

OK so last night I remembered that when I was in the eight grade at the age of 14 during February or March 2005, that I had insecurities because I imagined a imaginary woman in my head who sang songs from a uniquely female perspective; i felt like it was wrong to imagine that perspective. When I remembered that I started to worry that I might be transgender. It doesn't make any sense. I have never had an gender dysphoria, I have never identified as female, I have never had any desire to live as a woman and be treated as a woman, and I have never felt as though I was born in the wrong body.; I shouldn't suddenly identify as female/a woman or be confused about my gender identity. I am reasonably masculine and I have some stereotypical gay traits such some of the singers I am fans of. I do have a habit of irrational fears and worries in general..
