It’s a well-known psychological thing known as Doorway effect. It it to do with the fact that memories are more easily retrieved in the environment in which they were formed. In this case, short-term memory gets wiped when entering a different room.
Yep, a lot of the time if I go back to where I was when I thought of it, it comes back to me.
The doorway effect. https://en.m.wikipedia.org/wiki/Doorway_effect Known psychological phenomenon 😀
If you get a chance, some of the studies around it are really interesting.
Moving in and out of rooms you've created taps deeply into a very primitive part of human psychology, creating feelings of nostalgia and wonder and also in the case of minecraft--protection.
Another example is the "mind palace" method of recording information that humans used for centuries to record extensive oral histories.
You could think of the Doorway effect as a glitch from that same brain function.
A good method to help combat the effects of this is to "retrace your steps". Think/do whatever it was you were doing prior to whatever it was that you thought about and it will more often than not lead to you remembering what the task at hand was.
