I've not seen those but at Arles I saw an amazing dissolve sequence, to music, by Didier Conchonnet, of bilaterally symmetrical images of the natural world: mirrored by a vertical central line. I saw statues, faces, demons, gods... As I said to M. Conchonnet afterwards, if anyone had described it to me, I'd not have gone to see it; but happening upon it by chance, it was stunning, completely different from anything else I have ever seen. It sounds like a similar experience to yours, not in detail, but in emotional content.
