Can someone save Halloween for me lmao

I had broken my arm a year before this story. It had been my left arm (this is important later on in the story). I once played Hide and Seek Alone with a freaky doll I got as a toddler that I despised.   

On a Halloween night (I was ten btw), I fell asleep and set an alarm at 3 A.M. because I heard that if you wake at that time and then go back to sleep, you can lucid dream, and I really wanted to lucid dream for some reason. 
I woke to the alarm, but my room looked… different. I don’t know how to explain it. I stood up and looked around my room. I then opened the bedroom door and walked outside the door. I looked down the endless hall that was never there. I walked to where my older sister Ava’s room was. 
I knocked. No answer. I knocked again. Suddenly, I hear the creepiest young girl sing. I screamed and scattered into my room. I slammed the door, and the singing got louder. I pinched myself to see if I had been dreaming. A bit of pain shot through my arm. I sat on my bed to collect myself. I then heard a small, quiet voice whisper, “Hello, Bella.” Into my ear. My left ear. The scream that erupted from me was deafening, and I fainted on the spot. When I woke the next morning, it seemed nothing had happened.
Every Halloween night, I keep waking at 3 A.M. in the same, seemingly feverish dream. Even as an adult with kids, this doll haunts me. Every year, I try to figure out what happened. I constantly try different things in the dream, and the only clue I found was a small trail of my favorite crackers.
If y’all know what the actual hell is happening, please tell me!!
Best wishes, Bella The Albinism
