Dream of girlfriend

Ok so in my dream i had a troubled younger brother but in real life I don't have a brother. So one day he runs away and i seem to be the only one that cares even his non existent girlfriend thinks he'll be fine and will come back on his own, so I go out on the streets of my neighborhood and search and run to find him but no luck so I go to a big party with some of the people from my school and ask for their help but only one of my acquaintances offers to help so we run of to find until well into the next day when we get to a cowboy western themed festival where his girlfriend works and she again tells us he'll be fine until we argue for a bit and then I start crying and she then does as well
