Jamais Vu

I woke up this cold morning with something I couldn't remember.

I knew it was related to something I had learnt.

Something I said I WOULD never forget.

It seemed like the word Déjà vu was involved.
 Then suddenly, it was all gone.... just like that! A memory was gone.

Later in the afternoon.... even though I was able to recall my experience of the morning; when I was not able to remember something I said I WOULD never forget.

 I could no longer remember what the thing was,
what it was related to, or the word that was involved.

I hate it when this kind of thing happens, and its just like the word is at the tip of my tongue!
