The recent thread about Tulpas and their "Wonderlands" made me wonder if there are many people on Tildes that employ the Loci Method (since, as I understand it, they are functionally very similar).
For those that don't know it, the Loci Method is a mnemonic technique in which critical information is stored in a mental construct that is most commonly being visualized as a large building (hence the "Palace"). The process of finding the information within the building functions as a way to recall it, i.e. if you left your shopping list in your mental kitchen, then "going" to the kitchen and picking up the list makes you remember it.
Many people might know of this through the BBC series Sherlock, in which the titular character uses this method.
Personally, I have been using a mind palace for over five years now, when including the time I completely broke my old palace (more a bunker at that time) down to replace it with a new one, after I had become incapable of reliably using the old construct. My current mind palace is set up as a hybrid of the classic mind palace and a "Wonderland", in that it not only stores information within an extensive library, but also contains a number of amenities I can make use of when meditating. It is stylized as a temple carved into a snowy mountainside, think a combination of Paro Taktsang and The Tombs of the Kings.
To those of you who employ their own mind palaces, what are yours like?
