Spinning saucer with very bright lights. Quite large- about the size of a small house.

My friend and I stayed at the Meadowmount School of Music, and decided to stay left behind whilst most of the students went to a movie.  Thus the campus was quite dark.
                                     
We heard some pretty loud motor sound outside and wondered what it was. When we came out we saw a large saucer -like vehicle  hovering and spinning to a stop.  The light for immensely bright and we stared into it but couldn’t see anything.  We heard what sounded like a door close quickly and then it zoomed off, spinning in circles at a very high speed- higher than I’ve ever seen in my lifetime.  And it disappeared into thin air leaving no trace of odor or sound behind.
We did not feel afraid, but we both felt almost hypnotized or certainly mesmerized by it.
We never reported it as we both were certain no one would believe it.
