changing every day, every possible way
I’ve consistently noticed that my “home” in my dreams, though it seems normal during the dream, almost never resembles any place where I’ve resided (nor indeed any place that I recognize).
Now I find that the principle applies not only to dwellings! I had a dream involving “my” pistol, which resembled a Walther PP — a type that I don’t think I’ve ever handled.
Last night I dreamed of a small-caliber gun that externally resembled a Walther but its magazine fed into a revolver cylinder. The cylinder was missing one chamber (if a cavity can be missing); in the dream even this somehow made sense.
