I was driving home with my ex girlfriend around 1am on sherman way, north hollywood. i see an aircraft from far away and ask my gf if she thinks thats a helicopter. she replies " it looks too big to be a helicopter, it may be a huge airplane. i reply: you're right, it's an odd looking airplane. she responds: it's not moving at all though, it may be a helicopter i reply: it's too big to be a helicopter. we finally approach it and we find our self underneath an octagon/decagon shape aircraft hovering above us. underneath the ufo we saw a maze all over with yellow-orange lights coming out the maze. the ufo covered the entire street. i was incomplete shock i couldn't move to react.
