No sighting, but strange sounds and flickering lights after midnight.

I'm guessing at the date, it may have been as late as the early 1970s. The time of day is also uncertain, but was after midnight. I should also mention that since early childhood I would not go to sleep unless the shade in my room was pulled because I was afraid of "eyes" looking at me.
 I awoke due to a odd pulsating, whirring sound and noticed flickering lights on my window shade.  I called to my father, who was sleeping on the couch in the living room (due to my mother not feeling well), but all he did was mumble incomprehensibly. I was very fightened and simply covered up my head with a blanket. I don't recall if I mentioned this to my parents in the morning.
Time and date are approximate.  PD
