Light changing color in accordance with the traffic light.

I'm not sure of the date because it has been so long since i have seen it, but I was staying at St. Vincent's Children's Center on East Main Street.  I was in 6th grade at the time, and i was also living in the residential unit at the school.  I was in bed, along with my room mates ((deleted)) .  I saw a brilliant flash of white light and i got up and opened the window to see what it was. Then the white light faded out and I saw the traffic light outside was changing colors erradically...it would go from yellow to green then to red, and so on.  Then i looked up and to the left of it, and saw there was another light in the sky, changing colors exactly the same way.  The traffic light was about 50 feet away, and from my vantage point it looked like the UFO was about twice it's distance, hovering at maybe 150 feet. After i observed this for about 45 seconds, an even brighter white light shined onto me, and i had for some reason an intense feeling of joy, followed by an intense feeling of dread or fear.  The next thing i knew, the person who was on duty that night came into the bathroom and said "Are you okay, ((deleted))?  You've been in here for almost an hour."  That was the last time i'd ever mentioned it to anyone.  If you can, please leave my contact info in this explanation. I am an amatuer UFO investigator, and i still to this day haven't seen anything close to what i saw that day.  In fact, the event at that school was what inspired me to investigate UFO sightings.  If anyone wishes to contact me to tell me about anything they may have seen, they can email me at ((deleted))@aol.com.  Thank you for your time.
