Lighted round craft hovered and then dropped down quickly and shot straight out and away. While hovering, craft made a moaning sound.

We were travelling cross country and stopped at a camp ground for the evening.
It was very deserted there because it was the off season. We parked at the top of a hill. Just as my mom and dad exited the car I heard my dad say "what the hell is that?" He sounded afraid. I jumped out of the car and stood next to them and in the night sky very close to us was a round, well light ufo. I say UFO because I simply don't know what else to call it. I was very young, about 8 at the time and really in shock so I can't give much in the way of detail. The craft seemed to be hoovering in one spot and I do recall an eerie sound. The only time I have ever heard a sound like that again was during an earthquake. The only way I could describe it would be as a moaning noise that went up and down in pitch. After staring at the craft for a moment or two, it just dropped straight down very quickly and then shot off in a straight line and was gone. I have never really discussed this with anyone even my mom and dad. I think we were all too shaken to ever discuss it again. I have only one other memory of that incident. I beleive it was the next day. Walking thru a little country market with my parents. I was still very shaken and I honestly don't remember what happened between watching that craft shoot off and when I was next walking in the store. I don't think we were abducted because I watched it leave but I do seem to have some time memory loss. Thank you for hearing my story
