4 or 5 hazy white lights that made the shape of an oval that moved back and forth from east to west of a distance of about one mile.

At an altitude of approximately 1500 feet was 4 or 5 hazy white lights that made the shape of an oval that moved back and forth from east to west at a moderate to slow speed. It was running in an out of a dark cloud with lightning. When I first saw it, it was moving west away from the cloud. Then it slowed down and without coming to a complete stop it went east back into the cloud at the same time of the lightning strike. Then come out of the cloud for a distance of about 1/2 mile. It went back and forth in and out of the cloud as if to intentionally run towards the lightning then away from the lightening. It went back and forth 7or 8 times with a short pause in-between.
