A matter of definition

Déjà vu: a false sense that something new has been seen before
Jamais vu: a feeling or impression that something familiar is not familiar or is being seen for the first time
Presque vu: the erroneous sense of having something on the tip of your tongue, or that a mental epiphany or breakthrough is about to occur

I wonder if the French have a word for the strange feeling that something wonderful has just happened, but you don't have any idea what?
