Egg shaped figure floating twelve feet from ground with flashing lights.

It was an egg shaped figure that floated about twelve feet from the ground and it was a silver color with flashing yellow, red, blue and green lights around it.  It was very dark that night and from what I saw there was only one.  Later that night though there was a big flash that beamed throughout our house and awoke my parents.  The next mornining our neighbors said the same thing had happened to them and awoke them.
