White light shining down like a spot light then zipping back and forth and upward.

I do not remember the exact date, but it was sometime between late June and July 24th of 1994.  I was walking down the middle of the street with a friend at around 2:00 am.  Suddenly a light shined done on us from behind.  It was like a spotlight shining from a helicopter, only there was no noise that is associated with a helicopter.  We both turned around at the same time and saw a light hovering just above the tree line roughly 300 yards away from us.  When we turned the light seemed to instantly reduce in intensity, like it wasn’t a spotlight anymore, but just a light.  The object then zipped the left and upward, right and up, left and up and then back to the right and upward at a 45 degree angle and disappeared.
Witness indicates that date is approximate.  PD
