From the FAQ:

Jamais vu is a temporary sensation of unfamiliarity – it may include a sensation that something is new to you even though you’ve known it for a long time, it may include feelings of unreality, novelty or merely a lack of fluency. By far the commonest example is not knowing how to spell a very familiar word, or reading a word which you know very well, but finding it looks strange or it has lost its meaning (this is called word alienation). But other examples are common – getting very briefly lost in a very familiar place, a loved one looking different or like a stranger, losing your way in a very familiiar musical piece if you’re a musician, or forgetting what pedal does what when you’re driving.
