jamais vu 

Looking at something/someone you're familiar with, but having a memory of it, and no recollection of it. Everyone you know is somehow a bit of a stranger, and everything is new - but at the same time, you know it's jamais vu. Extremely confusing, and frustrating.

can't think of any

presque vu 

The intense feeling of being at the brink of an epiphany. An extremely frustrating experience, since a breakthrough never arrives - and you are left without it, hoplessly dreaming it will show itself to you.
