Several clusters of lights crossing low over head that made No sound.

I was watching Tv one night when I heard what I thought was a car alarm going off. Then I noticed it sounded like the alarm was coming closer, so I stepped out onto my balcony of the second floor of my apt. The alarm was still going off, I happened to look up and noticed several white lights, which were in four different clusters. The first cluster had four lights on it in a diamond shape as if the lights were at the 12-3-6and9 like a clock would be, moving slowly from southwest to northeast direction. The second cluster had only three lights, moving in the same direction, but the third cluster had four lights all moving together but rotating on an axis, in a counterclockwise fashion. The fourth cluster only had three lights, but it was a little different then the rest, because as it went over the highway it rotated slightly, and it reflected the orange highway lights from below. But it then appeared to have a single light in the middle of the triangle, It looked as if it might have been silver, it was the only one that I could tell that was solid. These crafts were about 500-800feet up.There was no sound at all as these things went over head, because by this time the alarms had stopped. It was a clear night I could see many stars, except in the middle of these clusters of lights. I have seenmany aircrafts and helicopters and this was like nothing I had ever seen. I don`t know if there was a full moon or not. I have been asked that before. There was a witness, he was the security guard at the apt. complex. He was outside looking for what was causing the alarms to go off. I reported this to a ufo network and was given several names, one of an aeronautical engineer, and one of a director of the network, who came to my house and even hypnotised me to verify my story.The Hypnosis session was recorded on tape. So he may still have them. I have names which can be gotten from me at request.
