floating craft 80 yds long by 30 yds wide, 6 spheres connected by cylindrical passages in the shape of a rectangle.

As a young boy in Ohio, on a clear summer day, I was standing in our front yard and my mother and grandmother were talking. I looked up to the south. From my position you could see about 50 yards across a vacant lot, then a raised railroad track, which blocked any other houses or sceenery. What I saw very clearly, just beyond the tracks and about, 200-300 feet high, was a huge craft, floating silently and slowly from west to east. This craft was about 80-100 yards long and 30 yards wide with 6 spheres connected by smaller cylinders. A sphere at each corner of the rectangle and a sphere in the middle of each longer side, all white to silver in color. I was amazed but not scared. I really had no idea of UFO's at that time. I pointed and looked back to my mother. I looked again and it was still moving across the sky. I looked back to my mother and grandmother to get their attention but they were having a serious conversation and did not acknowledge me. I looked back to the object and it was already fading out, and I watched as it simply dissappeared. I looked back and forth to mom and the sky and I didn't really know what to do. I don't know why I didn't shout out, I felt a bit paralyzed or mesmerized. What I do know is from that day on I started acting very much more mature, and became disinterested in kid stuff, and grew to have a 160 I.Q. and seem to have an amazing grasp of the inner workings of the world. I'm not saying that was even a result of this encounter, but something changed that day. I never talked about the sighting until years later with friends. And many years later I saw a craft with this same design in some science fiction movie, the name I don't know. The point being, I have drawings I made of the craft from 30 years ago, long before I could have possibly seen this design, and it begs the question did the movie's designer, accidentally design my craft, or have others seen this and made reports of it that could have been copied. I will include a drawing if possible.
Time and date are approximate.  PD
