Five quirks of memory that can mess with your sense of reality.
1. Déjà vu
"Already seen". The brief and fleeting experience of feeling as though a moment has been lived through previously.
2. Déjà vécu
"Already experienced". Déjà vécu describes a prolonged version of déjà vu, in which a holistic sequence of events is falsely remembered.
3. Déjà rêvé
"Already dreamed". The experience of feeling as though a waking moment has already been encountered during a dream.
4. Presque vu
"Almost seen". Known more commonly as the "tip of the tongue" sensation, presque vu refers to that frustrating feeling of grasping for a word or fact, but then losing sight of it immediately.
5. Jamais vu
"Never seen". Commonly associated with amnesia or aphasia, jamais vu describes the experience of not recognising a word, place or person, despite having already encountered them.
