I have no idea what these are. I know where they are. The sea in the top right hand corner is the Atlantic Ocean, the coast of Spain somewhere south of Huelva. But what are the objects across which the two human shadows fall? I can only assume that they are two dimensional extraterrestrials, barely perceivable to our senses, travelling on semi-visible levitating vehicles (if indeed two dimensional forms need to levitate).
If that is my shadow on the left, then the paler being must have passed through my right leg on its way to the beach, and yet I remember no injury.
As more and more of one's life recedes, such bizarre phenomena stud what passes for memory with increasing frequency.
