I’m yet to find a good solution for this.
I’m doing a project of memorizing a dictionary and in my first MP I ran into this issue, apparently a classic noob move. I had 25 loci and needed 50. My intuition said: just duplicate it with a different “vibe” and it would be fine, but quickly regretted it because of ghosting. I describe the process here.
I eventually moved the 2 instances/copies side-by-side and created a little story (competitor places, one female-themed, another male-themed), and am currently fine with it, but it came with the cost of reworking both places in significant ways. I don’t struggle with ghosting anymore, but only because I tweaked the ghost-prone areas a lot.
So: the urge to not create another mind palace came with a big maintenance cost, and in my personal experience, it wasn’t worth it.
I suspect a better solution for expansion would be spacial and not qualitative, as most people suggest.
For example, I plan to experiment with mirroring the mind-palace in some axis. But that doesn’t sound much easier brainpower-wise.
I suspect duplications/instantiations fundamentally don’t work well because of some neurological reason (the same reason humans are good at assigning space to memory contradicts the idea of reusing the same place as a different concept), but I’m curious to know if someone more experienced managed to hack the issue.
One caveat is that I have bad visualization skills, not exactly aphantasia, but it’s almost like I can render a scene in my brain but the monitor is off. I know it’s there, I could draw it, I could vividly dream about it. But adding vibes (“winter”/“summer”/“in flames”/“frozen”) doesn’t work well for me.
