I saw a large shimmering armoured riot like vehicle hovering off the ground making jet sounds with random flashing lights on

I was laying in my bed when I saw several lights reflect onto my wall from my window. This happens often due to cars and such. But it was extremely bright and went on for a few minuets finally I looked out of the window and over the treeline was a huge anti riot armoured tank like Vehicle but kind of translucent it was following the train line (that's among the tree line) but it was definitely hovering off the ground it was covered in seemingly random lights it was about 16 foot high and about the size of 4 carriages long. It was moving very slow I attempted to work out what lies inside the translucent Walsh but it was kind of shimmering it gave off a low pitch whirling noise kind of like large jet engines eventually it moved out of vision of my window but the noise remanned at the same volume for a while until it suddenly went silent .it definitely wasn't a train unless they've developed huge armoured floating trains made out of shimmering water and rando! m flashing yellow lights.
