Screaming or howling

We are in a house that could be a hybrid between where I live and the Twilight-vampire-mansion. Bright white walls, windows and corridors with smaller rooms. <PERSON> having a party, entering a singing contest. I wish her luck, and hope for the best. She is making new and other friends, and I accept that, I am glad for her. But I have the feeling that something will go wrong soon. And suddenly I am moved to third person view watching a kid in front of the small crowd's skin suddenly rip apart in the middle of his face, neck and stomach. I think he is me.(I am a girl by the way.) I can see the red flesh at the edges of his skin, but there is no blood or screams, no agonizing pain. Out of where his guts (in reality..) would have splatted out, rises a giants head. And now I am the giant, as the boy has changed into it like a butterfly growing from it is cocoon. Everybody is watching me, I am a little surprised and feel like the situation had just taken a turn of the worse. I roughly slide out of the room and hurries to a window. I now know that I know that something bad is coming. And am I right! In the shadows of the forest outside the dark window I can see a dark creature keeping watch over the house. When I understand it is form, my heart jumps. The familiar <PERSON>, from my first brief lucid as a kid, is out there, hunting me. I see it disappear among bushes, before I run over to a window on the upper side of the house. At the left sits my father. I make sure to keep close watched over the forest outside, and any suspicious shadows there might be, as I discuss the dinosaur with him. During this tense conversation I cannot recall, I somehow understand that it is my job as a giant to defend the house and the people that are inside. I must meet the dinosaur at it is arrival and hold him back with all my fight. Most of all I had wanted to hide in the corner of a locked room. I again spot a darker shadow in contrast to the trees, and know that the dinosaur is coming closer.The dinosaur is coming for me. It is coming for the glass of the window. I run to another room nearby, and know that the dinosaur had already leaped trough a now shattered window. I hear steps and feel it is presence like an unavoidable truth. I hear loud cracking noise as the T-Rex heads in the door separating us and get's trough. First, it is just his giant head in a hole of the door, with green shells and sharp teeth. Then it is his full-sized ancient body, as the once most infamous predator of the earth he were, standing before me. It is almost as looking into a gun pointed at your head, only this time it is highly aggressive and a little bit taller and larger than the average giant. We threw ourselves at each other, wrestling, but it did not last for long though. I had something he wanted to get; a glove. And the rest of the dream circled around me; The giant, watching a fighting and how-to-use-your-magic-glove instruction video together with another person, knowing the dinosaur could break trough the doors any minute.
