Is there a word for this?

You're driving home and you see a giant monkey statue in the playground that you never noticed before. It has obviously always been there. It's old looking.

You walk into the grocery store and realize that there's a little coffee shop to the left of the customer service desk. You've been shopping there for years and you were just there yesterday but you never saw it.

You visit your in-laws (for the 15th time) and you notice a shed sitting next to the garage. You ask your wife about it and she tells you that she used to play in the shed when she was young. It's not new.

Is there a word for this? Other than being clueless or absentminded?

Ask around.
