Does Google ever send a "Memories" from your photos and it plays music and shows your videos and some of your photos?

The day after my late boyfriend died, I received one of them from Google and it was photos of my late boyfriend. The music 🎶 along with his pictures coming on one after another freaked me out and made me cry.
Last week they sent my only live video I have of him and when I opened it up, there he was! Talking and moving around and actually it shocked me when I opened it because I didn't expect it see my deceased boyfriend alive and so close to my face.
I just received another one of them and it was of all of the pictures of him and I hugging together. And music playing with the pictures of us. Sad!!
How did Google know that he died and sent me memories of him when he was only gone for one day?
