Photoflash light, very intense, very quick, very deliberate.

I am a US Army Medical Officer, speaking from a childhood experience.  As an adult, the military has taught me to take on all challenges and to accept no fear, accomplish the mission. I am in my late forties and have done it all and seen it all.  Now before I die and leave this earth some day, somebody has to know this one little thing. I was about 7 and was in bed and the bright light flashed outside, so bright, the walls glowed. I covered up for a moment. Stuck my head out of the blanket and there was two things, big heads, large plate black eyes, slight glow looking dead at me. I hid in the blankets terrified for about 5 minutes, peaked out...they had their face right in my face. I have seen a lot of death and destruction in my military career, more than you can ever imagine, but this one childhood experience with this unknown thing lurking around my bedroom is the most frightening.
