triangular shape hovered over our heads

I was watching a tv show earlier about ufo sightings and I found it quite interesting due to the shape of the ufo and the dates of similar sightings...around 1989.
You see, around 1989 my brother and I both saw a ufo.
Basically, we were standing at the bottom of my cousin's driveway (In Knoxville, TN), waiting for the school bus.  It was always our waiting spot so we were standing there waiting for our cousin's to walk down the driveway.  It was your average morning when my brother and I just looked up and saw this ufo hovering just a few feet right above our heads.  It's an event I'll never forget because that night I dreamed the ufo shot rays down at my brother.  
My memories are vague to two brain tumor surgeries I had a few years later but I asked my brother about it years later.  He said it was triangular shaped and had lights all around the bottom of it.  I know there was no noise whatsoever nor was there any wind.  It was just the huge, silent thing above our heads...
In my excitement,I ran up the driveway to meet my cousin's shouting, "Did you see that?" The reply was,"See what?"  I turned around and walked back down the driveway to my brother where I asked him, "Where did it go?"  He simply said,"It just flew away."And that was that.
The reason I'm writing now is because I saw the show on the tv and they said there were several ufo sightings around 89, which was or was about the same year we saw it AND it was triangular shaped too..
We never really told anyone about it except for my cousins and family.  My parents never believed us and still don't.  My cousin believes me although she didn't see it.  I just wanted to tell someone ....Thanks for your time…
