Awoke to see red, blue and, white lights floating around the ceiling ran outside and seen a triangular shaped object hovering above the trees around house.

Awoke around 23:00 hrs. on Feb.18,1975, to see red, blue, and white bubble shaped lights on the ceiling of our bedroom. 
Went outside expecting to see emergency vehicles but instead observed a very large triangular shaped craft with pulsating red, blue,and white lights that were flashing simutaneously hovering just above the tree lines.  
The trees were moving but there was absolutely no sound.  And then there appeared to be window like openings with these angel like irredescent beings with large eyes looking out them.  
At 25:00 hrs. we found ourselves sitting on the floor in our living room the craft was gone and everything appeared to be back to normal.

We have no idea of what had been happening if anything in the two hours of missing time.
