Silent craft and many more smaller objects over rural Indiana.

I went to close my bedroom window and spotted a large, bright orange light.  I retrieved my glasses, expecting to see something on fire.  Instead, I saw an oval orange light throbbing in different shades.  I could tell by local landmarks that it was not on the ground, but barely above the northern horizon.  It was between the neighbor's farm and the next road, putting it within a mile of my home.
No sound.
The light came closer, growing in size, then suddenly started to drift eastward.  I turned off my bedroom light to get a better look.  That allowed my eyes to adjust.
I found the sky was alive with tiny specks of light zipping around.  Without movement, whatever they were could have passed for stars.
Approximately forty of them.  Some solid white.  Some solid red.  Some blinking red.  Some blinking white.  Some blinking both colors.  Zipping in all directions at various speeds, but some moving so fast, I could barely follow them.   Some would interact.
I remember one pair in particular that blinked furiously as they came together.  They spun around each other and then just zipped away at angles and speeds that seemed impossible.
I never saw the smaller lights interact with the larger light, but by then, it had drifted behind a nearby woods and was hard to make out.
I went to get a second witness to the event.  By the time I got back, all the lights had winked out.
Witness indicates that the date of the sighting is approximate.  PD
