This is somewhat based on the game Psychonaughts as well as the episode of Red Dwarf where a planet is Arnold Rimmer's mind. Quite frequently I imagine what happens in my mind a lot as if it was an actual planet.
For me, I feel like the center of my mind is a towering silver city, much like Minas Tirith from LotR, where there is a large divide separating the two sides of masculine and feminine qualities. Only a system of bridges establish connection between the two. Surrounding the city is a vast verdant plain that extends for miles and into the mountains. Overhead the weather is always overcast and quite frequently the clouds will rain. However the inhabitants of the city do not mind the rain, for whenever the rain pours down it means that the mind is at a state of peace. Several entities guard the entrance to the city including several characters that were long since used from my stories. Higher than them is the White Dragon which protects the core beliefs engine that resides at the very center of the city.
You don't have to mention anything too personal. Just have some fun and be creative.
EDIT at 10:35: There is one entity inside my mind that controls the erasing of memories, both consciously and subconsciously. His name is Oblivion and dwells in an unbeknownst part of the mind. Some of the inhabitants believe he lives adjacent to the Core of Beliefs but just unseen. Oblivion is a vast swirling fiery whirlpool. Any memory, feeling, or habit that is wished to be destroyed can be with his power, that is if said item is weak enough to become destroyed.
