This works, at least it does for me, and it saves me often because I regularly run into imagination deficit!
But I don’t do this for any information that I need to remember out of context (a phone number, an address, a name, etc) .
And I do this only with things that I know I have to revisit often anyways, and that are to be placed in a palace and in a way that the surrounding images can also help me, giving me ample chance to actually make the necessary conscious and/or unconscious associations, even when not making any sense at all.
Sometimes my imagination comes back early enough and takes over yee!!?, but most of the time the random image just ends up representing that info.
For example, I’ve got a lady on a reclining chair, but upright, and to my great surprise, it very quickly worked, representing the 4 letters question: Are you on vacation?
Or King Kong on a Trump Hotel reminding me of the sentence: what hotel are you staying at?
a gold bar has become this card suits sequence :
I can already see how my mind could trick me into believing that that is a mushroom.
Actually another trick I use that’s very similar to this, when my imagination doesnt cooperate well enough :
I pick a random image, first that comes to mind, let’s say a mushroom, and I play with what I want to remember and with mushrooms.
Maybe it would end up being one image with all of the following at first, but end up being much simpler :
Two legless guys (2 2) one in front of the other each pushing a bin with their weird mushroom-stem-shaped head^, one of the bins is v shaped and the other a U-shaped bin (v^2-u^2), and they’re filled with mushrooms and the two legless men are going to throw it all down a tube (=) where there are two giant humanlike cards, Aces (2as) actually, waiting to feast on the mushrooms.
