Very Bright Erratic Lights Appeared to Spread out and Jump Forward and Backwards

Went to the window when I heard a plane passing by the area a little after 9pm. I spotted the plane heading away in a South West direction then noticed another light I thought was a helicopter. At first the light was only a small point of light in the sky but appeared to be moving closer to my location following along MA Rt. 3 North.
After the plane was no longer audible I noticed no sound from the approaching light. The light was bright white with red flashes and appeared to be moving in erratic ways but in a direction closer towards my location. About halfway to when I lost sight the light about the size of a dime at arms length seemed to spread out creating a gradient of copies of in front of itself then snapped back to a more disk circle shape. I could not make out any detail of the underlying structure. The highway passes about six properties down from my location and watching the lights pass by it was about the size of a small plate at arms length. Estimating about 200 to 400 feet above the highway and I got the sense it was fairly large but totally silent.
Anyone driving up MA Rt. 3 last night between 9-9:30pm should have had a pretty good view of the light show.
