I was entering a school/university to disarm a bomb hidden somewhere on the premises. I knew this, because I was being guided by a woman who could see the future. Apparently there'd been a previous timeline where the bomb's gone off, and I'd died. Bummer. (Possibly, she was also a time-traveler.) I ran up some stairs where everyone else came down. I remember thinking that at some point someone was going to try and stop me, thinking I'm a student and I should be headed for class. I don't recall how things went, but I was successful this time and the bomb was presumably disarmed. Anyway, when it was all finished, I met up with the woman again. She was a beautiful, had long red hair, and was in her to late '20s. I quite liked her, and we got along well. I didn't want this to just "end", lose touch and miss this opportunity to get to know her better. Before I woke up, I had a vision (where the line between unconscious dream and conscious imagination blurs) of her lying in bed with me.

All I remember was being in a building, and fighting a video game 'boss'. The whole setting was 100% realistic, not all all like a game, but I could retry the fight as often as I wanted. The boss was just a person, but taller and very strong. Conventional weapons didn't seem to hurt him very much. I had this bomb, it looked like a German stick grenade from the second World War, but it had multiple explosives. I say 'bomb' and not 'grenade' because this thing was utterly devastating. I think I put the grenade in his backpack (or somehow attached it to his back) while distracting him. Then I ran away very fast. The explosion pretty much vaporized the large, multi-storey building. I assumed this killed the boss. I tried that fight a few more times. At some point, the explosion happened underground. I ran outdoors, yelling to people to flee as fast as they could, as the blast radius was easily a kilometer. We were on the street when the bomb went off. The ground literally started cracking open, releasing hot gas from the explosion. Someone yelled at people to avoid the cracks.
