Beam of light while living in military housing

I was 8 (37 now) swinging in the park on base housing and a beam of light came down from the sky.  It made a buzzing sound.  I looked up into the night sky and there was no visible aircraft to be seen.   
Few nights later my mother told me I woke up crying which to this day I can't remember.
There was also police called due to someone seeing an intruder outside my window.
Witness indicates that the date of the sighting is approximate.  PD
