Outside of my window there was a really bright light that looked like a star but it was much more bright started moving and flashing

I looked out of my window and i saw a really bright light that appeared to be a star just much brighter it stayed there still for a while until i got up to my window to have a closer look it then started moving as the bright light dimmed and started flashing red it looked like an aeroplane however they don’t emmit lights so bright and stay still so its impossible it was one. I filmed it as it flew away and went to tell my mother as she came to my room to check it out the bright light i saw before it left was back and what i had just witnessed repeated itself with my mother there to witness. I keep seeing strange flashing lights similar to that one since that day too small to be planes.
