I was at the toilet when i heard a strange sound like in movies or something. i opened the window and saw that object in the sky not that far away and it was huge. first it looked like a jet but then i realized that it was not so i took my binoculars and observed the object. it was a big object with the shape of a mix of spear and a triangle. it had wings like a jet but it was different. at the back of the wings there were things that looked like propulsion but they were white and didn't look like they used fire. it looked like they had multiple windows and at the windows there were entities that looked like a mix of human and something other. because of the distance and darkness because it was late, i couldn't see the color of their skin but they had strange head shapes, everyone was different. they had something like our hairs but not hairs and that was like long hair. the ufo had black and dark red dash patterns. the sound it made was like a mixture of the batmobile and a jet after about one minute and 30 seconds, the ufo started to move like a space shuttle in movies and flied away and up to the sky until i couldn't see it anymore. during that, it got louder. the propulsions could move a bit so the "space shuttle" could fly up and it was very fast.
