Jamais Vu Situation Recognize Door Word Describes Familiar

This word describes a familiar situation which is not recognized. 

(Means "never seen")  

It is often considered to be the opposite of déjà vu and it involves a sense of eeriness. The observer does not recognize the situation despite knowing rationally that they have been there before. It is commonly explained as when a person momentarily doesn’t recognize a person, word, or place that they know. Chris Moulin, of Leeds University, asked 92 volunteers to write out “door” 30 times in 60 seconds. He reported that 68 per cent of his guinea pigs showed symptoms of jamais vu, such as beginning to doubt that “door” was a real word. This has lead him to believe that jamais vu may be a symptom of brain fatigue.
