After some dramatic incidents in my life and lack of sleep, I walked into my apartment. I recognized it, knew where things were, but it was like it was another person’s apartment, not mine. It was an eerie feeling and i was about to walk out again, but forced myself to watch TV until the feeling of otherness disappeared.
From Wiki:
“In [psychology](h, jamais vu (h: [ʒamɛ vy]), a French borrowing meaning “never seen”, is the phenomenon of experiencing a situation that one recognizes in some fashion, but that nonetheless seems novel and unfamiliar.”
“Theoretically, a jamais vu feeling in a sufferer of a delirious disorder or intoxication could result in a delirious explanation of it, such as in Capgras delusion, in which the patient considers someone they know to be a false double or impostor. If the patient sees themselves as the impostor, the clinical setting would be the same as the one described as depersonalization; hence, jamais vus of oneself, or of the very “reality of reality”, are termed depersonalization and derealization, respectively.”
