Still bright light, stayed still for a while, started to flash and move in odd ways

The white light was hovering, looked like a planet at first but extremely bright. I tried to guess then planet, pulled out my phone to check the star map to confirm before realising it was total cloud cover overhead. As I went to take a picture instead, the light started flashing and moving. The white light continued to flash and other lights began flashing around it in many colours. It began to move quite quickly towards us, then changed direction unbelievably quickly and sped off in the opposite direction. It disappeared after a couple of minutes, but not because it travelled too far away. It just vanished. There was absolutely no sound whatsoever. I never managed to get a photo as it was moving too quickly and changed direction too quickly.
