11/12-1956 9/10PM Painesville/Willoughby OH over Lake Erie Rectangle continuous void 5x9 black mirrored window like.

When I was around 10 years old traveling in my dad's car going west along Lake Erie near Ashtabula/Cleveland, at the Painsville/Willoughby border, probably around 1956, hovering above Lake Erie, there was a huge rectangle about 5 miles long and 3 miles wide.
 It was around 9/10 PM either in November/December.
 As I raise my right arm now it would be about 2-3 o'clock from the Lake Erie horizon N-NE from the Painsville/Willoughby line. As I look at it through the L of my thumb and index finger now as an adult, the rectangle void was 5" High, the length of my Index finger and was 9" Long or Wide the projection from my thumb angled out including the length of my thumb from the bottom of my index finger.  It was almost like the size of a business envelope resting on the L angle.
 This triangle was empty looking as though it was a void. The odd thing was that the stars that were surrounding the object were shining as usual in the sky, there were no lights flashing or edging the object but and blackness of the void was blacker as though it was a black mirror which was different than the sky with the stars. It looked like a door into another dimension.
 My parents told me it was just a lack of stars because there was no moonlight and insisted I close the car window. Several years ago when I started to hear the people on your show talk about the triangles I was hoping someone would talk about rectangles but so far haven't heard anyone talk about them.
 However, if you put several triangles together you can have a rectangle.
 I will never forget seeing this void, this emptiness.
 Even at that age I felt as though it was Big Brother watching.
