Oval multicolored object that had sharp-jagged twinkling lights around it. Green, red and gold lights.

This siting still gives me the goose bumps. I was only 6 or seven years old, was staying at my grandparents house in Strandburg, SD.
I had been sick with the flu and had a fever, so I awoke in the middle of the night to get some water. While I was walking to the bathroom I peeked into my parents room and saw out theirr window a VERY VERY unusual object in the sky. Even though I was sick with fever and the flu, I am positive this wasn't a halucination! The mintute I saw this Creepy light, I knew that is wasn't supposed to be there. The only way I can describe it was this twinkling, strobing, fashing, circular, object that had either green(light) on the ouside twinkling or on the inside-I can't recall for sure. It also had gold twinkling flashing lights on the inside-or the other way around(opposite the green). This very strange light was not moving across the sky  fast but was twinkling or strobing or flashing very quickly-almost like an animation or a video game graphic. This object was probably 70 degrees up of the horizion and probably pretty far away-although VERY VERY noticable! I looked at it for only a short time and was frightend back to my room. I never told anyone else about it-until now...
Do you have any ideas what this might have been?  If you need anymore information I will fry to give it to you, although I was very young and don't recall all the exact facts, I know I saw something very unusual that night and I will never forget the creepy feeling a got when I saw it...
Thanks!   ((pseudonym deleted))
