Darkness Beyond Time

I was running from some monster in some kind of hallway. When I got to end of hallway there were doors and I closed them tightly. I saw I have MP5 in my hands. I thought : wait what am I doing here ? Why do I have gun in my hands this must be a dream. I decided to go back and kill that monster. When I opened doors There were few houses in front of me and I saw a green mountain in distance. I saw that monster on street. I thought since this is a dream I could kill him easily. I decided to summon atomic bomb. I detonated it like 20miles away from here. I saw that houses were shaking in front of me. I saw a mushroom cloud in distance and then I said to my self If I don't make some kind of barrier I am going to be caught in blast too. I made a barrier with my hand which successfully defended me against atomic blast. I saw all things around me disappearing. Everything was black. There was no single thing around me, only blackness. I looked at my self. I was all shining white. After that dream started fading away and it ended.
