Dream of girlfriend, kids

Me and my girlfriend s kids are sitting in the backyard of our house playing, she comes out and says dinner is ready. The kids run inside with her, but as I walk through the door everything changes. All the furniture vanish, my wife and kids aren't there. The whole house looks like it's been abandoned for years, the windows are all boarded up and everything's covered in dust. I run to the front yard and scream there names, no one answers, I walk back inside the house, and walk to the corner of the room where there's a dusty old chair and sit down. When I do I feel something in the chair, it's a revolver with one bullet, I take the gun point it at my had and pull the trigger, then wake up
