I Think I Had This Dream Where I Was My Dad As A Kid With A Younger Version Of My Paternal Grandma

It was when I was younger, but I'll always remember it since at first, I thought I was just some random kid eith a random mother, I was walking near this retro 70s-80s supermarket, then I played with a tennis ball in a park with a fence, grass, and slides before waking up. I didn't think anything of it at first, but I later saw photos of my paternal grandmother when she was younger, and she looked exactly like the woman in my dreams. I always thought it was weird, especially when I got older, and into the AC series which had you resting the lives of your ancestors, which reminded me of this dream
