Total eclipse of the senses?

Somebody please explain the Bonnie Tyler "Total Eclipse of the Heart" video to me, please. Doors slamming open, men dancing around in loin cloths, choir boys with glowing eyes (taking bright eyes a little too literally perhaps?), biker guys clasping fists to their chests while prancing on steps, Bonnie Tyler in a white dress fleeing through long hallways with red curtains blowing in the wind? Okay, maybe I missed something. Always like the song, now I am sorry that I ever saw the video. Was it a horror movie gone wrong?
