This was a lot of fun, reminded me of Goosebumps novels! I think I would have loved this as a young teen looking for spooky stories.
The one thing is that from an aesthetic point of view, I feel like the music, font and pictures don't really match? But then again it's hard to find non AI creative commons photos that also match your vision. Same for music and ambiant sounds. It's already impressive you made this much by yourself.
Anyway, I had a good time and I enjoyed your writing.
