light seperated into four parts and flew away at right angles

I was looking out the car window and saw what I thought was a planet.
There were no other stars or lights in the sky.
I could not tell how far away it was.
All of a sudden it seperated into 4 equal size pieces and each flew at perfect right angles and in perfect synchronized time to the four horizons and disappeared.
Then there was nothing.
It lasted about 5 seconds.
The speed was unbelievably fast.
Witness indicates that the date of the sighting is approximate.  PD
