Markus,
When a mentalist predicts your imagined scene using priming techniques, you can regard the primer as the cause of the imagination which, in turn, can be regarded as a memory of the primer. Similarly, a future `primer' (perturbation in the essay) can be regarded as a (retro-) cause of your imagination which, in turn, can be regarded as the (future-) memory of the primer, if the imagination can be used to predict the `primer'.
As you can tell, my idea rhymes with the notion of "retrocausality". However, retrocausality alone is inconsistent with `future memory' phenomena; The underlying ontology must also be non-mechanistic/non-IVP - as I explain in the essay.
Best,
Yehonatan
