long cigar shaped UFO

I got a real good look at this cigar shaped UFO. It was a hot summer evening and i had just finished supper with my parents. As i left their home to go back to my appartment,i had come up to this stop sign to take a right turn.(I was 5 minutes from their home)I made a right turn and looked over in this field to my right that had cattle in it. I looked up and saw this round light greenish milky white light. I stopped my car and thought to myself, WHAT IN THE WORLD IS THAT? I leaned over toward my passenger seat and just watched to see what it was going to do. It was about 50 to 75 feet off the ground and looked like a long cigar with no wings or tail,and was dark colored with a round light on the front,like a flash light would have . As i kepted my eyes on it i could see what appeared to be heat coming off the sides of it,and it had a faint humming sound,plus it kinda vibrated as it was moving. It was moving real slow. Anyway, i couldn't take my eyes off of it, and then all of a sudden it just disapeared right before my eyes.Like the blink of an eye, it was gone. I thought to myself then, WHERE DID IT GO? So then i turned my car around and came back to my parents house to tell them what i had seen. They told me that they have never seen a UFO, but there could be some out there. So i left and started back home and decieded to stop at the people's house who owned that piece of property to tell them what i had seen. I wanted them to know in case something had happened to any of their cattle. Well finially when i got home and ready for bed, because i had to go to work the next morning. I heard this humming, buzzing sound over the top of my appartment building. I thought to my self, oh no that UFO followed me home. I grabed my little dog and covered both of us up with the covers. I was scared then. Well the next three days i was in a complete daze.I felt really weird, like i wasn't all together there. After the third day of being in a fog. I awoke in the middle of my sleep and set up in my bed! and kin da sceamed.After i screamed, i saw this bright light flash across my bedroom and right out the window it went. I was back to normal, the foggy feelings i was experiencing had left me.
