Blue light that rapidly grew, broke off into 3, "fell" a small bit, and disappeared

I was standing in my parents' driveway pulling my keys out of my purse and I glanced up at the sky for a few seconds. A tiny bit to the east, and around plane-height in the sky, a bright bluish-white light, about the size of a small star, appeared and rapidly grew brighter and bigger until it was around ten to fifteen times the size of a large star (such as the ones in the Orion's Belt). It then broke off into 3 smaller blue lights that "fell" a tiny bit in the sky before completely vanishing. The large light grew for about 4 seconds and did not have a tail nor did it seem to be moving. However, the 3 smaller lights "fell" a tiny amount for about 1 second each before vanishing and they each had tails. None of the lights had defined edges, they were round however they were very glowy which made them seem a bit blurred. It was completely silent outside, there were no people outside, no cars running, and no dogs barking. I watched for about 2 more minutes and nothing else happened. The whole experience happened too fast for me to pull my phone out and take a video or picture.
