cant describe what I saw? And when I try something deep inside tells me not to!!! sorry.....

Well first of all I've never told anyone this before! I'm 37 yrs old now an this happened when I was 17,It changed me! Got me thinking of alot of things I was a tough kid in those days I thought. that night I'll never forget!!! Well, the experience started the day before. My mom made me get a hair cut,an you could'nt wear a cap at school! So I skipped I spend most of the day in the "nature trail" that was part of our school. So, I looked for a place to "crash" til school was over.When I woke up I did'nt have a watch,an I did'nt hear the bell ring! So I was'nt going home! I went to my grandmothers house. visited with her, an ate ! It was getting late! my grandmother reminded me that I had to go home. So about an hour later I left. The only thing on my mind on the way home, was I wonder if she knows I skipped! Well, I got to point where I decided to take a short-cut threw the "nature trail" The next 15-20 mins I will never forget!!! I started walking there were dogs barking at me from homes near the trail, I could see the path alittle from the moon light.It was kinda cool or I was just scared! i had picked up two pretty big rocks & was carring them with me, in case there was something or someone in the woods. I was getting close to the entrance so I started to hurry alittle, then right there in front of me was something that i could'nt even describe I thought it was a joke at first but it started to move an it did'nt move right i mean who the hell would look like that & move like that in the woods! I raised arm Like I was gonna throw the rock! & I've never seen anybody move that fast, I started to scream things like I'm gonna kill your (F)ing ass!!!! an ran right for the entrance or exit! I ran about 15-20 feet & turned to throw the rock, An I saw A big bright light that shot straight up in the air!!! I ran til I got home, When I got there I just got in trouble for coming home kinda late! I know my life then to you probably seems weirder. i did tell a friend of mind but he did'nt believe at all. well, th! ats my e xperience with what I call now "my close encounter". I know what I saw! an i wish & pray that I did'nt because I cant get it out of my mind! and I am really scared inside!!!!!  thank you...............…
