Abandoned school building dream

I’m driving down this one street by my parent’s house and I see my younger on the sidewalk along this street. She says she needs a ride and gets in. I think she needs a ride to work. We get to a building that looks like an abandoned school building. We are inside the school building walking around, but then suddenly we need to leave. We start walking down the stairs together. As we’re walking down the stairs, we see a small child on the landing below us. The child is hunched down on the ground. I look back and see my sister and her friend behind me waiting. Now there is plywood covering where we had come from, where there was just an open doorway. At this point we are trying to find out how to get through the covered doorway, but nothing we do can move the plywood. I decide we need to go past the child. I hop past the landing and the child. I look back at the child and the child slowly stands up from his hunched position and starts screaming at me. I run down the stairs and am able to get out of the front door. I look at the door and see now there is caution tape around it. I run out, find my car and get in. I’m driving down the dark road lined by tall trees, waiting for my sister to come out. Eventually my sister comes out of the building and climbs in the car with me.
