Dream part 2 (fragment)

We're all in a hall, for some reason. Maybe it's my old nursery school hall that they used across from the church, back in Tonbridge - I don't know.
The hall is spilt into two half, facing each other, door on the left of me in one section. Everybody is here. Literally, most of everybody I've ever known in my life - old school friends, new school friends, people I haven't seen in years.
Alice is sat opposite me in the other group, first row, facing me. I'm second row. Some music comes on, and Grace gets up and invites her to join in a line now formed, dancing to Brown Sugar by the Stones -- even though it got introduced as 'Summertime Blues', which Alice incorrectly told me was 'Summertime Who' after I leaned in to ask her what she was doing. And although I was having fun, I refused to go up and join them.
So she goes to the back of the line and starts dancing. Meanwhile, George May - who is sat to my right - starts trying to kiss me and I have to put a pillow inbetween us to stop him. Eventually, he calms down and I have to laugh it off, assuming he was only messing around, only joking about. Nonetheless, I decide to get some air and see how my hearing is - as by this point, the music is rather loud.
So I go outside - which is, for some reason, a small road in North London (not a real road, but for some reason I knew it was London). And after a few steps, I turn a corner and put my fingers in my ears to see if I can still hear okay. Taking my fingers out again, I noticed that my hearing was still slightly off - it sounded very much like I was underwater. But as I continue further and further down this alley I know found myself in, I notice my hearing starts to get better. Deciding I better turn around and head back in, I started heading back out the alley again, when I notice a man on his phone walking past at the top of the alleyway, back on the main road. He has a beard and sunglasses on, but that's all I can tell.
Then there's an explosion. I turn around to see if I can see anything at the bottom of the alley, I just see people running.
So I head back to the hall to see if they got hit there. Surprisingly, I'm not in any hurry back, although as I get closer and closer, I become more and more aware that the explosion occurred in the hall. I pass a man and a woman, and - though I don't recognise the man - I know him to be the boss, the man in charge of the events and hear him say something like, "We need to handle this correctly." For a second, I thought they might stop me going any further, but they didn't - just walked right past me.
As I got to the entrance, people were carrying others out - whether they were dead or alive, I don't know. So I got in and start to worry about Alice. I knew pretty much every other person at that hall, but all I wanted to do was find Alice. So I head up the staircase to the right side of the entrance and follow this small group up the stairs (who, I assume, are also looking for survivors to take out, etc.)
"Anyone seen Alice?" I asked very calmly, trying to be assuring that I was well aware of the situation, and our chances of finding her were as good as our chances of finding anyone else.
Kash or Harry or someone is a couple of steps above me, looks down and says something I can't quite remember. But then I hear a female voice saying, "She seems to be doing alright."
It was Gaby. So we hurry up the stairs until I see Gaby's head on the left looking down at the ground. At first I thought she might be looking at Alice's corpse, but when I finally laid eyes on her myself, I saw that her eyes were open and she was moving. Though, for some reason, she couldn't talk.
"Hey baby, hey Alice," I said - making sure to smile, so as she felt safe that I was here now to help her.
I look down at her face, covered in dirt and there is a big pool of blood forming around her mouth, coming from her nose. Her body is covered in debris, and I am unable to tell if she can get up or not. So I decide to try and carry her out.
I assume that I would have asked the guys for help assisting me on my way out to get help, except that I woke up. The possibility of this happening, of me losing her was already too real. The dream was already too real.
I woke up.
