Monkeys

I was in a building with lots of corridors and rooms.  I was walking with one or two more people.  They mentioned to me that there was danger around because the monkeys were angry.  We walked through a room that was full of monkeys.  They looked at us angrily but did not attack.  We walked slowly to avoid getting them angry.  We left that room and walked down a hallway.  Some of the monkeys followed us and started chasing us.  We ran into another room and it was also full of monkeys except these were bigger like gorillas.  There was a door on the other side of the room and if we made it to the door we would be safe.
