A look before I die (please read)

Last night I had this dream it was weird. Throughout the whole dream my left hand/wrist looked like that, my wrist slashed and rotted and decayed to the bone. At the end of the dream though me and 3 others, 2 kids one adult, where on top of this bridge, that's what those metal strips are in the pick, the beams we were crawling on. I was scared shoot-less because well its a bridge with cars and water below us. The adult is laughing and joking so was one of the kids. (kids = my age, I'm 14) I'd been nearly falling off for a little bit but then all the sudden the other kid, the non joking one, falls and I just watch her descend to her death. The adult tells me that if I don't start moving and doing such an easy thing as crossing the bridge the way we were she'd kill me (the bridge almost seemed like the golden gate bridge). The image you see above is like a screen-cap through my eyes, right before the dream ended. It was the weirdest thing, I looked down at my hand, just laying there, and right after I look down, smile, and jump. Upon descending I wake up, a death grip on my left wrist.
Please note: I am not suicidal in any way possible, the scar on my thumb and back of my hand are actual scars I have in real life. Nor am I depressed in any way.[color/]
