Could it be that the times when I didn't know what a firefly was were happier?

I thought I was a shining star.
I never doubted it.
I didn't know that I was a bug.
It's okay anyway, because I am dazzling.
I thought it was a star fallen from the sky.
A small star that grants wishes
I didn't know that I was a firefly.
It's okay anyway, because I will shine.

I often see a reality that is not always as positive as these song lyrics.

Could it be that the times when I didn't know what a firefly was were happier?

Is the world so stained that it keeps making me think about reality?
