Bright light hovers over Higgens Lake, MI one night1974 or 1975 during deer hunting season Nov.15th - Dec.1st

This is my fathers version of what we saw on the night of november between the dates of November 15th to December 1st 1974 or 1975. At about 9pm-10pm at Higgens Lake,MI I was up deer hunting with my son when we both observed an extremley bright light. It was the brightest light I had ever witnessed, it lit up the inside of the cabin just like daylight. It was hovering over the lake just above the tree tops. Everything was extremley still, almost like being in a vacum. I was extremley afraid and I told my son to put his head underneath his covers. I was afraid that whatever it was might be coming in to get us if it saw us. I to buried my head underneath the covers. After what seemed like a few minutes, I looked out the window and the object was gone.What bothers me is that we never discussed it the next morning with each other. Not untill recently have we discussed in depth what we witnessed that night.
Date is approximate.  Please see son's report!!  PD
