This Is What Happens In Parallel Universes

I have seen other worlds in dreams

I have seen in dreams other worlds perhaps. I would tell something about other universe/world/parallel reality/other dimension: 1. I have seen a world where there is one spiked very very long(at least our solar system length) horn type protruding form their planet which was white in light always but in dark space. There was like tons of humans in back suits moving all around that spike as if that holds some significance for them. 2. I have seen a world where humans like us were being hunted with snipers in open areas just like some queer sport 3. I have seen a world where the apartments and buildings are very very strange and mysteriously crafted like in alien life and all are going in line as if we are going in some spacecraft with time as dimension. 4. I have seen a world where 3 people like Gangam style suits disappearing from one place to other and stealing mysterious artifacts from witch type places.
