UFO-approx 1965-67 Bowleys Quarters MD, Silent flat oval shaped, glowing softly, colored sphere.

I was approx 5 or 6 yrs old (1965-67), we lived in Bowley’s Quarters in Maryland. Our house had a large open field that ended in woods. My aunt & uncle lived in the house next to us, large field separated our houses. I remember the weather being a cool summer evening; remember the grass being cool on my bare feet, light warm breeze, just before dark.  I was in my Aunts kitchen when my mother took my hand and followed my aunt into her back yard where the other children were, everyone was standing still, staring about 4-6 ft maybe at one, maybe more, flat oval shaped,  glowing softly sphere, that was silent. The colors inside reminded of the colorful swirls you see in a soap bubble. I remember thinking to myself if I could touch it my hand would go right through it. It felt like it was watching us too. I stood there holding my mother’s hand, motionless, like everyone for what it seemed like an hour, more likely 15-20minutes. I remember hearing someone whisper “what is it” but no one answered, maybe for fear it would go away, we all just stared in silence, then all of a sudden…like a camera flash, it was gone? I never recall our families ever talking about it? Maybe the older ones did.
I’m now 45 years old, recently, talking family and friends about UFO’s unexplained things etc... I asked my older sister, who was there that night, if she'd remember the lighted sphere or was I just recalling a stupid childhood dream that stayed with me? She immediately replied, "Oh my God!! That is so weird! I was just thinking of that the other day and telling a co-worker about it. I had never brought it up before, just one of those things, you store away until something brings it to mind. I though it would be interesting to know if anyone else in that area around the same time recalled seeing this
