Screaming or howling

I am walking with my sister at night in this populated area, the ground is red brick and there is a large clearing of this surrounded by restaurants, a water fountain and shops. Suddenly something sucks me into the air, and I am put gently on this thing on the side of a building just in front of where we were walking, it is a sarcophagus of some sort. I realize that my clothes have been changed, I am wearing egyption shit. I also find significance that the sarcophagus is rubbery feeling at top which I feel means it will be opened soon or used soon and this frightens me so I try to walk on it as carefully as possible, I walk forward and lean over the edge and yell for my sister. She yells to me what had happened? I tell her I do not know and that I will try to get down, but then suddenly my sister screams and points at this thing that appeared just above and in front of me. It is what appears to be a flying man with this black head piece over his head, looks like a falcon head almost. I freak out and try to back up on the thing but he comes at me and I do not know how to explain it I knew he was going to get me so I jumped off the edge knowing he would not let me splat, but I just wanted to say goodbye to my sister for the last time. It is like I knew and then I floated into the air and then the guy carried me off way into the air and then back on top that thing I was on but it has changed a little bit, it is longer and more people are on it dressed like egyptions, we are lined up at the edge performing some sort of ritual, Then I suddenly seem to snap out of this trance and realize I do not want this fait, so I run to the edge of this sensitive structure and grab onto it and everybody slides to where I made it collapse a little, most of them get angry with me and tell me to stop now, but some of the girls have broken out of the spell from this and we line up again and we do it again but its more effective because more people and the thing begins to collapse, the falcon guy becomes enraged, and all the girls and I are awake and we run up the collapsing thing and make it to the solid roof of a building and then the thing crashes to the ground. Then the guy flies after us, and we race over top buildings and I run fast then leap as far as I can to the next building, it seems some of us do not make it and we turn on each other trying to make it, but some of us are pulling for each other. I make it to the last building then climb down and hide in all this tall green plants and bushes and trees.
