This is something that happened to me since i was little and i was always very concious about but never even seen it mentioned by anyone else.

Whenever i stay still in a seated position for a long time i get this weird smell in the inside of my nose. Its undesrcibable maybe vaguely similar to old dust but not unpleasent nor pleasant.

It doesnt happen when im in bed, i have to be seated, and as far as i remember im always watching a screen when it happens.
It used to happen a lot when i was little and watched tv. Now its when im still at the computer for a logn time (at least 3-4 hours)

what the fuck is this? any explanation
