There's memory clutter, which reminds you of an important person, achievement, or event from your past. I think memory clutter often gathers in the homes of people with some degree of depression. And then there's I might need it one day clutter, in which people hang on to stuff in anticipation of an imagined future. Among these folks, I've noticed a recurring theme of anxiety...Maybe it's possible that the stuff we own and obsess over is the physical manifestation of the mental health issues that challenge our minds. --p29.
