deja new 

Essentially the opposite of déjà vu: coming into contact with an object, having an experience or encounter, or meeting someone that feels completely "first time", new, original -- but definitely isn't... there is some definitive proof that you have been in this situation before: others have witnessed it, or even worse, your own notes belie your having had this experience before.

Somewhat akin to having "a senior moment", or being pre-Alzheimer's, but more public, thus more embarrassing.

I was reading a book's passage, and was blown away by the writing and was going to write something down as a comment, then turned the page and saw I had once before already done just that, years ago. I felt a shimmering of "deja new".

deja news 

the strange feeling that one has witnessed or heard this news previously be it due to archives, monotony, or actual deja vu.

I can't watch tv...I'm so stifled by the deja news.

That feeling when you can with certainty identify something or someone that you have never seen or experienced before!

When first saw it I got this strong feeling of dejanew, I recognized that I had never seen it before!
