"doppelganger".

Naranasan mo na ba na makasalubong o makita sa isang lugar ang iyong kaibigan o kakilala nang hindi inaasahan dahil malinaw sa iyong kabatiran na ang taong iyong nakita ay kasalukuyang nasa ibang bansa o dili kaya'y iniwan mo sa ospital at malubha ang kalagayan kung kayat imposible na makasalubong mo siya sa oras  ding iyon ilang minuto pagkalabas mo ng ospital. At mas nakakapangilabot pa na isang uri ng ganitong kaso ay ang masalubong o makita ang mismong sarili mo sa aktuwal na lugar di kalayuan sa kinatatayuan mo na humhaharap sa nakaambang panganib o aksidente. Paano po natin maipapaliwanag ang nakakapangilabot na bagay na ito. Para po sa inyong kabatiran, ang kakaibang bagay na ito na malimit mangyari kaninoman ay ang tinatawag na "doppelganger".

Marami ang nagsasabing ang kakaibang pangyayari raw na ito ay isang hudyat, babala o "premonition" para sa isang taong nakatakda nang mamatay.

Ang  doppelganger  ay salitang german na ang ibig sabihin sa salitang ingles ay "double walker".Sinasabing kapag nakakita ka ng replika ng isang taong kakilala mo o mismong sarili mo sa  isang lugar, itoy masamang pangitain o signos ng isang kamalasan o kamatayan.

Ayon sa mga mananaliksik  ukol sa bagay na ito, dalawang bagay ang maaring tumugon sa mga katanungan ng mga taong naniniwala dito. Ito ay ang ispirituwal na paliwanag at ang siyentipikong pag-aaral ukol rito.

Ipirituwal na Paliwanag 

Ayon sa wikipedia, sa artikulong pinamagatang  Human Disguise,

In the Old Testament apocryphal Book of Tobit, the Archangel Raphael takes on human disguise and the name of Azarias.^[12] (Child and Colles note that '[...] he appears as a mere man, an archangel incognito as it were".^[13]) The Book of Genesis tells of three angels visiting Abraham in human disguise (Gen.18),^[14] and two visiting Lot in Sodom (Gen.19).^[15] Philosophy professor Peter Kreeft has asserted that when an angel wears its human disguise, human beings cannot penetrate the disguise due to the superior abilities angels possess; Kreeft cites as proof Hebrews 13:2: "... some people have entertained angels without knowing it."^[16] Child and Colles summarize: "The angels in the Old Testament were known to be messengers of God, sent to do his will, usually invisible and mysterious, but sometimes coming without wings in the guise of men."^[17]

^{Malinaw ang gustong ipaliwanag sa artikulong ito, na noong panahon ng mga karakter sa bibliya, madalas bumababa ang mga anghel mula sa langit na nasa anyong tao upang maghatid ng mensahe at kadalasan nga napagkakamalan talaga silang tao ng mga tao noon tulad ng nangyari sa sodoma na nakasulat sa Genesis19.}

^{Maaaring dalawang bagay din ang dahilan kung bakit nagkakaroon ng doppelganger kung ang pagbabasehan ay ang isipirituwal na paliwanag dito.Una, maaaring ang nakikita natin na replika ng kaibigan natin o mismong sarili natin ay ang anghel na naatasan mula sa itaas na gumaya sa ating pigura upang maghatid ng babala upang tayo ay makapaghanda sa anumang kakaharaping mabigat na sakuna  o napipintong kamatayan.Maaari rin namang ito'y sadyang di naiwasang close encounter kay Lucifer  o sa mga alipores niyang masasamang anghel na itinapon dito sa lupa  na kilala rin  ring magagaling na shapeshifter at mandaraya. Ginagaya nila ang histura ng kanilang mga bibiktimahin minsan ito'y para ilihis ang kanilang paniniwalang ispirituwal at minsan naman ay sadyang pagkitil ng buhay ang kadahilanan ng kanilang pagdo-doppelganger.Kaugnay nito,  ayon parin sa artikulong Human Disguise;}

  St. Augustine and Christian scholars of that age agreed that the Devil could manipulate a person's senses to create illusions in the mind, constructing from particles of air fake human bodies that seemed quite real to those who saw them.^[18] John Milton's poem Paradise Regained has Satan disguised as an old man.^[19]

Scientific and philosophical investigations

 Left temporoparietal junction

In September 2006, it was reported in Nature^[2] that Shahar Arzy and colleagues of the University Hospital, Geneva, Switzerland, unexpectedly had reproduced an effect strongly reminiscent of the doppelgänger phenomenon via the electromagnetic stimulation of a patient's brain. They applied focal electrical stimulation to a patient's left temporoparietal junction while she lay flat on a bed. The patient immediately felt the presence of another person in her "extrapersonal space." Other than epilepsy, for which the patient was being treated, she was psychologically fit.
The other person was described as young, of indeterminate sex, silent, motionless, and with a body posture identical to her own. The other person was located exactly behind her, almost touching and therefore within the bed on which the patient was lying.
A second electrical stimulation was applied with slightly more intensity, while the patient was sitting up with her arms folded. This time the patient felt the presence of a "man" who had his arms wrapped around her. She described the sensation as highly unpleasant and electrical stimulation was stopped.
Finally, when the patient was seated, electrical stimulation was applied while the patient was asked to perform a language test with a set of flash cards. On this occasion the patient reported the presence of a sitting person, displaced behind her and to the right. She said the presence was attempting to interfere with the test: "He wants to take the card; he doesn’t want me to read." Again, the effect was disturbing and electrical stimulation was ceased.
Similar effects were found for different positions and postures when electrical stimulation exceeded 10 mA, at the left temporoparietal junction.
Arzy and his colleagues suggest that the left temporoparietal junction of the brain evokes the sensation of self image—body location, position, posture etc. When the left temporoparietal junction is disturbed, the sensation of self-attribution is broken and may be replaced by the sensation of a foreign presence or copy of oneself displaced nearby. This copy mirrors the real person's body posture, location and position. Arzy and his colleagues suggest that the phenomenon they created is seen in certain mental illnesses, such as schizophrenia, particularly when accompanied by paranoia, delusions of persecution and of alien control. Nevertheless, the effects reported are highly reminiscent of the doppelgänger phenomenon.^[3] Accordingly, some reports of doppelgängers may well be due to failure of the left temporoparietal junction.
