I was looking out of a window and i saw a flashing light in the sky that caught my eye so i watched it to see if it was a ufo or a plane or helicopter but it started making really sharp turns and the flashing lights got brighter and then the flashing lights stopped as it got closer it was tilted like it was facing the ground in front of it i got excited but i also felt sick and like i was going to fall over every now and then but that eventually stopped a few minutes after i lost it because it flew past the window and emitted no noise
