Hey what do you guys think of this? any comments?

You know that saying that says before you die, you see your whole life flash before your eyes? Well, this saying wasn’t entirely true for me. Maybe because I’m not dead yet or maybe it’s a dream. No, if this was a dream I probably would have woken up by now… I must be dead or dying at least. Anyway, for me I didn’t see my whole life flash before my eyes, I saw well something—well I guess you can say different. It all started 2 years ago, when my parents moved our whole family to Montana for work. They said that the old great west would be good for us, but all I saw was a bunch of barns and run down ranches in the middle of nowhere. Plus I didn’t get reception on my phone, so I couldn’t text my miserable new life to my best friend-Alica. our first afternoon at our "home" was horrible, I haven’t rode a horse in years, but now that’s pretty much my only transportation since both my parents were working that summer, which means they got the car, and I was stuck with my grandma and grandpa on their ranch. But, they did have a nice trail to explore...that’s where I met Steve. He had green, hazel eyes and dirty blond hair. Everything about him was I guess you can say perfect, almost too perfect. He reminded me of what I left behind back in California; my home, my friends, my school, my whole life and my two best friends ...Jake and Alicia. They were my whole life and we did everything together. Jake even saved my life once and wish he was here to do it again. Anyway, on a Saturday evening while I was getting used to riding my horse on Oak Trail, my horse bucked me off because she was spooked by a snake. Causing me to injure my ankle. That's when I met Steve. Luckily, he was riding on the same trail and found me. He offered to take me home that night and I thought that he was a nice guy. Though, there was something about him that I wish I would have found out sooner. Steve attached my horse sugar to his saddle and carefully guided us back to my grandparent’s ranch. He was different than what I imagined a boy who lives out in the middle of nowhere would be, but he was perfectly normal, well...normal isn’t how I would explain him now, but then he seemed like a average kid living in Montana. Anyway he helped me clean up and feed the horses, it wasn’t till now that I realized I know pretty much nothing about him, and he never had to be anywhere. I guess that explains a lot now, but I was too busy admiring his great listening skills to notice. My grandma said his was the nephew to old mr.granger. She said that mr.granger is an odd man, he plays his piano all day till starting at 6:00 am and ending at exactly 6:00 pm he barely stops to eat. She warned me about Steve, and now I wish I would have listened. That night I had a dream. I was in a forest. This forest had dark green pine trees and a small the creek that ran right through it. It was nearly dusk and the sun was quickly disappearing. Everything seemed to move much more quickly than usual because soon enough it was completely dark. Surprisingly, I didn’t feel tired but, very energetic. Then floating right in front of me, I saw something so beautiful and so unreal I couldn’t help look at it. This beautiful creature was a butterfly. It had huge wings that were a pale pink with splashes of gold sprinkled on the rim of each wing. The butterfly also, had one yellow spot in the center of its right wing and the center of its left wing. I know it doesn’t sound like anything unique but, it was. Unlike most butterflies, this butterfly had a glowing light that surrounded it much like a nightlight. Somehow, it put me in some kind of trance while I was walking because; before I knew it I was on a beach. Though, it was still dark, the twinkling stars that reflected on to the water made the beach glow. As, I walked closer to the water I saw a girl, who seemed unconscious, lying next to the water. There was also, a boy sitting on his knees next to her, looking now. And, as she got closer she realized that the girl was her and the boy was Steve.(end of prologue)

I would presume that you are still in school and are not considering publication. If so, then I don't think that a full critique would be in order at this time.

But in any event, clean up the grammar.

The main thing about a prologue is that it must suggest or foreshadow where you are going.

Your prologue suggests impending violence. Is this your intent?

"I must be dead or dying at least" suggests someone under severe sedation. Again, is this your intent?

well me in my friend wrote this for fun.. ahahah and she made that part up so im not sure.. But, i think what she meant to do is state the future of the story in the beginning or something like that. I'm guessing shes trying to do what stephanie meyer did in the beginning of twilight.... im not sure

I have one word: PARAGRAPHS.

Just to add to what has already been said, try and stick to one tense. You're kind of jumping all over the place and it makes it difficult to focus on the story itself.
Try and limit your use of 'anyway'. If you reallly can't think of another way of moving forward in time, or back to the present, a thesaurus is your best friend.
