Is it normal that i think that this was a memory from a previous life?

Earlier, I dreamt that I was a young (I'm guessing 10 years old) boy and I had this elementary school teacher who I was very attached to. Her name was Mrs. Shirley. In the dream, I only lived with my grandma (neither of my biological parents wanted me), so I looked up to Mrs. Shirley as a mother-figure. She was very loving and kind to all of us. She was a very fun teacher as well. We were like her kids, you know? Mrs. Shirley didn't have any kids of her own and I was her favorite student.

However, Mrs. Shirley's husband took her back behind the school one day and attacked her. I recall him cutting her face up. I went for help, but by the time the monster was done with her, Mrs. Shirley was no longer with me. In denial of her death, I looked for her calling her name "Mrs. Shirley!"

The News covered the arrest of Mr. Shirley and where she was buried. I visited Mrs. Shirley's grave in the hopes I could "squeeze life back into her" through my tears, pleas, and hugs but to no avail.

I cried a little when I typed this. :'(
