I was on a bus which was heading to a place which I knew of in the dream, but I cannot remember now. I was going over this sort of bridge and turned away from another place, this disappointed me because the bus usually goes to this place but didn't this time. The bus was driving towards an entry to some sort of building and a big van type truck was coming out too, it was an awkward situation and the bus had to return back a bit so it could get through, which was the problem as the other driver wasn't in much control of the vehicle. The vehicle drove up where our vehicle came from and I had this sort of premonition that it was going to crash into one of those vans that have the hazardous fuel. I don't remember getting out the bus, but I remember entering the building and my premonition took place. People were panicing and I told them to hide behind something, this is where it came to me that this has happened before and the last time it happened the fuel tank exploded creating a mass explosion which reached this building, a lot of people died but I knew I could stop this from happening again. I told people to stay away from the windows as I remember that being a dangerous place last time. However, the fuel tank never exploded and people started having a go at me saying how I lied but I said that I just did it for their safety as this had happened before. I'm pretty sure this was a separate dream: I was going back to school already because I was told I had to complete some test, I don't remember much of this part, just the room which was a basic science looking room. I do remember someone that I know trying to fight me, he grabbed me and I didn't fight back but just pushed him off me and he fell to the floor, he kept trying to grab me still and I did the same thing. I then remember being on the way home with the same guy and another person who I used to talk to a while back. We bumped into my friends back from school whom I hung out with, I remember one of my friends going on about how they were still doing youtube and were getting quite popular.
