3 bright colored lights comming straight at me...

I was about 13 years old. I was walking back home from a friends house about 10:00pm.I was about a block away from home when I saw 3 lights up in the sky. I kept walking and it got closer and closer. I could see now that the lights were rectangle and flashing one at a time from left to right. One was white, the middle was red, the other ode was blue. It was close enough to me now that I should have heard rotor blade niose if it was a helecopter, that's what I thought in the begining. It comming towards me until it was about 50 ft away  and about 70 ft off the ground. Buy this time It was starting to get a little scarry. I heard a humming noise but nothing else. It was colse enough that I should have been able to see someone inside but the lights were too bright. It had stopped at about what felt like mabey 30 ft away, then the lights stopped blinking and came on steady. In about 5 seconds they shut off and one very bright spot light shined down on the ground in front of me and was comming my way. That was it...I ran into a trailer park I was in front of and hid. I sat there shaking for about 20 minutes then snuck back out and had a look. It was gone. If it was a police helecopter it would have followed me and sent a car out to see why I ran, but i don't think the police had copters back then, and besides I would have heard the blades and as close as it was it should have been pretty windy. I ran home and never seen it again. I didn't go out at night for a few weeks either. All these years I have been waiting for someone to report the same thing. I never have. Mabey there is someone out there that has. I would like to compare stories.
