Mindscapes are a concept that I have found really interesting lately. My own definition of a Mindscape is "The visualization of the way in which ideas/concepts, memories, and emotions are stored within the mind, and the visualization of their retrieval and interactions". It's similar to the idea of a Mind Palace, but those are more associated with memories than they are emotions, and when prompted to describe their Mind Palace, people seem to be more likely to talk about a library or some actual palace than what they actually experience.

To summarize the information I've found so far:

A lot of Mindscapes are very unorganized, and the people describing them to me find their own to be a pain to navigate.^[1]
They are often very physical (possibly because I'm prompting them with the word scape).^[2]
Most information is held visually, not auditorily or by other sensations.
Very few people don't have any Mindscape at all. The only people that I've asked that report not experiencing any kind of Mindscape are my parents and my sibling.
I'm worried that Mindscapes could increase compartmentalization, specifically with library-like ones where ideas are books or scrolls, not something more amorphous like algae or different colored streams of water.

I would like to learn more about Mindscapes, so if anyone has some good resources, or even better if you could share your own experience, I would appreciate it a lot. In the comments I will share some more examples that my friends have given, so if you're interested they should be there.

Here I'm specifically referring to my friend who said to me "memories feel like portals [because] there are surface level entry point memories, and then there are tons of memories that i have to go through like [a bunch of] portals to go deep enough for the one i want"

It's possible that imagining a Mindscape as physical in the sense that it's held within three physical dimensions might be decreasing the dimensionality of associative structures, or otherwise increasing compartmentalization.
