Electric impulses in thoughts, manifested in dreams and deja vus. Just about everyone has experienced the odd, fleeting sensation of deja vu, often described as the sense of reliving something previously dreamed. Ironically, while that definition implies precognition, many who stand by that explanation are also staunchly opposed to psychic phenomena in general. When deja vu is married with another mysterious, yet scientifically real, autonomous activity – dreaming – it lends itself to an acceptable explanation. A quick internet search reveals that most instances of deja vu are reported to last only a few seconds. My experience confirms this observation. Wikipedia summarises several theories about the sources of deja vu, but fails to adequately address its most uncanny aspect: that it produces more than a sense of “having been here before.” A dramatic deja vu’s impeccable predictability is stunning, if transient. It’s not a sense of having known what’s going to happen after the fact or even as it’s happening, but rather having a significant and notable awareness of precisely what is going to happen just before it happens, in a cascading fashion. A few weeks ago I experienced the strangest deja vu. At the onset, time fell away and seemed to cease altogether. I estimate that for about five minutes I was simultaneously immersed in the past, present, and future. Now I can’t begin to entertain the notion that I’d dreamed this situation before; my dreams are realistic, yes, but in a way that isn’t duplicated by “real life.” There I was, sitting on the sofa, listening to another’s recollections unfold entirely as I anticipated (so to speak; it’s difficult to describe something outside of time sans a time reference), in what would become the longest deja vu I’d experienced. The other person involved in my five minute deja vu nearly always resorts to science’s euphemised heavy hand, aka Occam’s razor, to explain most phenomena residing outside the canonic worldview. Yet for him, deja vu is the experience of something he predictively dreamed long ago. In this way deja vu is a future reflection of a past dreamstate, exploiting the universality of dreams.

Screenshot: Business Insider VEĆINA ga je iskusila barem jednom u životu. Osjećaj da ste neku situaciju već doživjeli, neke stvari ili mjesta već vidjeli, poznatiji kao deja vu, zbog kojeg se pitate: zar se ovo već nije dogodilo? U videu koji donosi Business Insider, producenti Michael Moffitt i Greg Brown donose odgovor na pitanje: što se događa s vašim mozgom kada doživite deja vu. TEKST SE NASTAVLJA ISPOD OGLASA Većina ljudi doživi deja vu u dobi između 15. i 25. godine života što ukazuje na to da je osjećaj povezan s razvojem mozga. Također, deja vu je teško istraživati s obzirom na to da nastupa iznenadno i ne događa se tako često. Ono što je poznato, tvrde Moffitt i Brown jest to da je deja vu povezan s aktivnostima medijalnog temporalnog režnja, dijelom mozga zaduženom za dugoročno pamćenje, a koji se odnosi na pogrešku u neuronskoj vezi između rinalnog korteksa i hipokampusa. Druga istraživanja upućuju kako deja vu doživljavamo pri smanjenoj aktivnosti medijalnog temporalnog režnja, što objašnjava veću učestalost ovog osjećaja kod osoba koje imaju epilepsiju.
