Magical flying school

Date: 3/9/2018

I wake up walking the hallways of a school. Kids are filing in for an assembly. I join them and sit down next to a class that I don't know to feel safe. The announcer asks for a volunteer. I get picked. Something happens and the school gets attacked, thrown into a huge waterfall. I don't really get that part but somehow we survived and land in a foreign place. We get rescued by helicopters. We come back to school only to realize it was overtaken by dragons and I've lost my bag, so I have to find it where ai left. I have a class though so I can't and I panic. I don't really remember much else.
