Dream of animals

I was on an island that was filled with tall grass and weeds. There were three people with me; my dad, a girl and a Hispanic boy. we all were walking through the grass when something began to chase us. we all ran into a barn hiding in the grass. In the barn was a door that i could not unlock; but my dad could. after the door was unlocked, we all went through it and found creatures and animals that weren't from earth.
