Screaming or howling

I feel myself going lucid, like an energy going up my body, I feel like I am "falling" in lucidity but I suddenly feel a weird knot, like something close to my stomach, a ball forms? I wake up before I can totally get control of the dream. I am in a warehouse with my elementary school class, big windows in front of me show a field and some trees in the distance, sun is coming up. We start doing a dance and I somehow take over, leading it, everyone dances around me in synch except I am doing different moves. It ends with me doing the Sun Salutation as the sun rises in a golden haze. Afterward I walk to a teacher to my left who commends me for the dance. I say that it was not too good, offering a far too simple view of native cultures as close to nature, a modern view imposed on them. I follow a man with a brief case down a city street. We enter a large glass, modern hotel or office building. I think he is going to do something bad, like rob the place or extort money. As he does that I go up the transparent glass elevator. In the hall there is a bunch of people sitting and standing, like a reception for someone, or a party. I talk to the CEO, a young, handsome guy. He says environmentalist have put a bomb in the building. I panic, instantly accepting my fate. I will die here. Then I suddenly gain some courage. Can I escape? I go down the elevator, almost out. In the lobby by the front door, sun is shining through the windows, I see a young woman in a white baggy t-shirt and a sign, an environmentalist protesting. As I exit I whisper to her "I agree with you." I walk briskly out, the bomb can go off any second. As I cross the road and head toward the train station I hear a rumble, behind me a cloud of dust and chaos. I run toward the central train station, people are screaming and trams are crashing. Inside the train station, trams are crashing through the walls, and so are buses. I do not know where to stand, any false move and I am dead. I stand paralyzed. A mutilated and almost blind bus driver comes out of the break room, he is been out of work for years but because of the emergency he can now work as everyone is now preoccupied. I see a rat catcher that looks like <PERSON>. He says he is killed almost all of the 5000 rats in the train station, but the remaining 800 left are as tough as nails, the fittest survive the longest.
