Oh yeah. 
The accumulation of all your leftover junky thoughtstreams about your many failures and weakness. Story later today.
We’ve lived in the same house for years which has a large laundry room on the second level. The dryer, like all, has a removable lint filter (cleaned often) which has behind it a tube leading through the wall to the outside. Sometime during growing up I was told that if you didn’t keep that tube clean, it was a fire hazard. Then I’ve seen thirty foot wire brushes designed to clear that pipe. (Okay, it was that Air Mall catalog always in the front pocket of your seat with the marshmellow gun.) Then there is the occasional unexplained house fire.
Think of this pipe as a room in your brain. This room is full of bad stuff about yourself that you remind yourself about and worry that if enough lint accumulates . . . Oh, who knows? But it will be awful. So we need to worry.
On the occasion of a new dryer I called in a chimney sweep to clear out the pipe, which after all these years, had to be disgusting. I left him to pull the old dryer away from the wall and get to work.
He called me in a few minutes later.
”Clear already?” I asked.
“Yep.” He stepped to the side of the pipe hole in the wall. “Do you see that light, ma’am?”
“Yes.”
“That’s daylight. There’s no pipe here accumulating anything.”
Turns out I made the whole story up.
