Dream of building, kids

I was in my daycare but is was just one big building painted tan with nothing in the room except for a few toys for the kids and a train track running through it. i didn't recognize anyone there except for my one friend. Then the teachers came running into the building yelling at us to get on the bus as half of a bus build up on the train tracks. We ran to grab our backpack that just randomly appeared. Running behind the teachers were like meat creatures. One of them picked me up before i got on the bus and was about to eat me when i said dont eat me eat my friend so it put me down and i got on the bus and he went a grabbed my friend everyone made it on the bus except my friend at the bus pulled away from the building and i saw the meat creatures holding on to my friend.
