There was a science fiction short story many years ago with the premise that all those extra hangers, socks, etc. that accumulate are a form of mimicry by alien life forms, like a walking stick insect. Wish I could remember the author, Laumer, Leiber, Kornbluth, Sturgeon, hmmmmm...story had a somewhat sinister twist too, watch out for those spare socks!
I remember that story. I believe the infant 'aliens' looked like paper clips, then grew into wire coat hangers, then became bikes as adults.
I think the story you mentioned was written by Philip K. Dick
Or all the sea with oysters by Avram Davidson
