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.

I was in a car, with a former classmate of mine (Nathan) and a few others. There was a discussion going on between Nathan and the others, and it was getting pretty nasty. I feel he was being bullied. Despite the fact he hates me in real life, I felt sympathy for him. I wasn't sure which "side" to choose.

School again. I was in a large, strange room deep in the school building. Looked more like a large cave than a room. There was a giant statue in the room, at least 30 foot tall. A person was holding a speech to a bunch of people, me included. Then, there was a shootout. I was being shot at by several enemies, but time moved slowly so I could dodge the bullets (looked like a scene straight out of "The Matrix"). I shot all 10-ish enemies faster than they could blink. Then, it turned out it was all an "act", a scene for a movie or something. All the bullets in my gun were blanks. I unloaded my weapon, and noticed the last round was real. But it wasn't a normal bullet. It was made of glass, and filled with a green liquid. I think I moved it too abruptly or dropped it, because a mechanism triggered and the liquid turned red. The bullet made a beeping noise. The beeping got faster. I got out of there like lightning and ran for the exit. Right after I had run out of the building into the open air, the whole building exploded in a massive fireball. My carelessness had killed dozens of people. Including my "co-star", a girl I had (fake) shot during the scene we were playing earlier. She appeared in front of me as a ghost, and she scolded me for killing her. Another girl appeared in a flash, a fiery superspeeder (like the Human Torch of "Fantastic Four") and ran into the school. She hadn't realized it'd blown up. She wasn't hurt though, thanks to her fire-based ability. An eclipse appeared (the landscape looked very fake suddenly, like a badly animated Photoshop), which signified I'd fucked up badly and there would be consequences for my actions.

EDIT: During the shootout in this dream, there was another point where I could not pull the trigger. It wasn't "heavy" this time, rather the opposite, loose - like the springs inside the pistol's mechanism were broken.
