We have a linen closet that for a time in my childhood was emptied out and made to serve as the "Nintendo room", containing an NES hooked up to an old Commodore 64 monitor. I still associate that fabric/crafty smell with 8-bit gaming.
I can’t really describe it, but sometimes after sneezing I get this very pleasant smell in my nose for like 2 seconds. It’s what I would imagine the world’s most expensive bedsheets to smell like. It doesn’t happen with every sneeze, but the smell is consistent and has been for many years. Unfortunately it only lasts for like 2 good whiffs.
