I read this really great story by Bradbury years ago that has always stuck with me but I can't remember the title, or find it anywhere.

It is about a world in which a silent "crew" move around preparing the "set" for every place the protagonist goes, and the moment he leaves they take it down without him knowing it. He thinks he's in reality but he's always on a set that has just been erected.

Any help would be greatly appreciated.

"Yesterday Was Monday" by Theodore Sturgeon.

Basis for an episode on The New Twilight Zone called "A Matter of Minutes."

This is what I was looking for, thanks so much!

Glad to help.
