disk 20 ft round silent zig zag and hovered very strange to watch silver color

went out side and saw a disk above a shed 30 or so ft up 15 to 20 ft round it moved in a zig zag pattern no sound at all and hovered around. It was strange to watch got sort of scared when it move towards  and above me, then the strangest thing happened  I was taken up in a spinning real windy motion wich was very breif. not much to remember except a bright light and heat across my forehead. had no blood on my self when I all the sudden was in the front of the house again but have a transverse cut wich took 7 stiches   about ten years ago I worked at hughes aircraft, and had  hit my head  when they took an x ray  they really scrared me by asking me about that mark seems like they could see some kind of line  running to the penal gland never had another one done and didn,t even go back to the doctor after that. because it kinda jogged my memory of that day. I have seen some after that occurence over the years but no other contact as far as I know.
Date is approximate.  Please note reports from New Hampshire during the summer of 1965.  They are very similar to the report above.  PD
