Dream of caught, chased

I was standing at a little boy's bedside. He was fast asleep and I could instantly feel a connection between us. However, I could not see his face. The room lolled like my former friend's room, but the exit was different. It was peaceful for only a moment when a monster suddenly appeared and tried to harm the little boy. I immediately switched into attack mode a chased away the monster. As I go back to the boy, it comes back. This cycle happened several times before I was exhaughsted. And just as I think the monster gave up, it came after me! I tried my hardest to make it leave, but by that time, I was too weak and tired to fight back. And soon enough, the monster caught an killed me.
