As we drove in the darkness suddenly 2 lights appeared. I and my girlfriend (who is now my wife) looked up into the dark sky. We both were driving our motorcycles.

I urged her to stop. When she did she got in panic, and drove away quickly. I stayed behind to watch it. First both of us stood in a column of light, every sound was gone even from our motor cycles. 
As I was standing there, it came towards me, me standing in that light. My wife saw it looking back. it was hanging there now and than gliding away, lights were couloring from wite to rose and purple as if it was talking, again every sound had been vanished (cars from the motorway and factories in the neigh-berhood).  
It was great, but we dare not to tell anyone. 
The next day all over Holland had been sightings it stood in the papers next day. As quick as it appeared it glided away in fast speed, faster than a meteor, from one second to the other. I never believed in it but my life and thoughts and my wife's thoughts have been changed since that night!!! 
Keep up the good work, We know some are watching us, maybe for the good!!!  (I hope)  We never told this to anyone.  Like to give you this information after all those years.
I ever hoped to see it again, unfortunately we haven't..…
