Dream About Shooting In Big Plaza

I don't remember where I was, but it was some big plaza, like an old school mall. It was me, my husband, and my youngest child. We had gotten word that someone was shooting up the place, and a few times the shooter had seen me and Madeline, my youngest child. For whatever reason, he had to shoot us. I remember feeling nothing but pure terror. I wanted to hide. In the end, before I woke up, they had already locked down the place. And me and some other shoppers were in the locked down area, and we were right by the exit where there was the sliding glass doors, and they were letting us out one by one. I remember feeling very tense, and for whatever reason, the car seat didn't work, or whatever. We came to find out that the shooter had tampered with people's vehicles prior. I ended up waking up from my alarm, but prior to all that, the last part of the dream was me, my husband, and my youngest standing in the glass area, waiting to get evacuated out.
