Dream About School Musical Party Confrontation

In my dream, i was with the cast and crew to my school's musical that we're working on, legally blonde. In it, we decided to have a little party outside the school at the little outside tables. Everything was well until we realize that kim and josue go missing. We try calling their names, but no one answers or comes back. I take inaaya and elianah with me to the "bathroom" because im scared, and while we walk there, we see josue on the ground unconscious. We run towards him, but there was a shadowy figure trying to attack us in the meanwhile. Kim was suddenly there too, and she was already trying to fight and run away. All four of us get away from him and go back to the rest of the group were we explain everything and then my dream ends there.
