Dream of died, grandfather, grandpa, mad, mother, number, space

The dream starts out in my house. There is my mother and sister on the couch and the light is on. Then the dream changes. Now I'm in a bedroom which seems like the attic. I'm lying in this bed, my sister is in it with me and my grandfather too. My grand ma is sitting in a chair at the end where my grand pa is. My grandpa is lying on his stomach and starts turning and moving all over the bed. We figure he's dying and I think that if I died I wanna die with god the last thing on my mind. So grandpa is still tossing and turning and I keep saying that he looks peaceful and then he dies and then the number 70 pops into my mind because god promised to give 70 years. Then it's like he disappeared and where back in the room. This time l'm asleep and sister wakes me up so seems evil and keeps trying to take all the space on the bed. Then the dream shifts to these girls it's summer and there having fun riding there bikes. There in the street in the middle part between the yellow lines and the concrete in their path is making the area the tires can sqeeze through smaller and smaller. Next it's this mini cliff in there way so they jump down it with there bikes. Again there going down the street then a mad men with a gun with a ski mask all dressed in black starts shooting at time with a machine gun. I see them trying to get away and I notice one girl gets shot in the back then the dream shifts again. Now I'm back in middle school but I'm still the same age and which is high school age and I walk in there wearing different clothes then everbody else. My shirt was red then one of my old classmates makes fun of me and says he bets that I can't even spell the word dynamite. Then I get a dictionary and on my way I notice this couple at a table there studying or something. Then the dream shifts to the news. The reporter says that there are different gods and dreams that they give you are long and lengthy and you have to choose which one to believe.
