Psychological, perhaps? Doorways represent a separation in space -- perhaps they create a similar separation or break in the consciousness?

Leaving thoughts in rooms is a bug in the memory palace system.
Just put the thought in the room you're going to before you go.

This has the answer you seek op

Its a psychological phenomena called threshold syndrome, basically your brain relates doors to another set of things, rules behavior. Etc. That "reboot" can make youbforget things. Solution: Go back tobthe other room and back out.

i heared its like this: your brain connects different thoughts and memories in our mind. not only that, but as well what we smell, see, feel, where we are etc.
now you get the idea to go to the kitchen and get some snacks. the moment you leave the room a new part of your brain/mind loads, the one of the floorway, and later then of the kitchen. the idea with the snacks however had a connection with the livingroom where you no longer are, and thus it just slips to the back of your mind and you forget it for the time being.
if you then go back to the living room there is good chance you remember what you wanted to do because the connection witht he livingroom to the snacks is reestablished and makes it easier to remember

It's the same with how revisiting a place where you had an experience can make it easier to recall that experience.

Technically anything can trigger a memory, a sight, taste/smell, sound, feeling or thought. A location is usually more than just what you saw there (more stimuli). Memory is quite strongly linked to physical position.

It's from the change in context. I don't know as it's ever happened to me, but I also don't know that it would've happened to you if you hadn't been told that that happens to some people when they walk between rooms.

I take a sideways look at life. Imagine if we didn't have doors. It'd be like we were all living in one massive room. Spooky.

It's called the doorway effect, for whatever reason, it causes a psychological change that makes you forget things.
It's nothing spoopy and mystical, now go read a book and stop being retarded.

Yes sir

It's a real thing. I remember reading about it somewhere. Doors are considered, "event barriers" so in your head when you walk through a door your brain considers it as a new event, at least partially separate from whatever you were doing before. This mental separation is what may cause you to forget about whatever it was you were going to do in that new room.

this is the correct answer.
