strange lights ,no sound,spotlight like thing shining down on us.

My brother and I were sleeping in the back yard, one night on the farm I was not asleep and looked towarded the east saw 3 or so lights moving slow going north I thought they were helicopters, but they made no noise, got scared and covered blanket over my head.  
When I looked again there was a light very close up in the trees shining down on us and what I recall, no shadows from the trees (we were sleeping in a grove of trees behind the farm house) no shadows which was very strange,  
I tried to wake my brother up but he wouldnt wake up. I covered over again and do not remember any thing until the next morning,  I do not remember if I told any one the next day or not?  I do not think this was a dream it was just to real and I still remember it to this day.  Have not had any other experiences.
Witness indicates that the date of the sighting is approximate.  PD
