One idea mentioned in the article that I've seen elsewhere is this:
"The gist, then, is that someone is “himself” because countless mental artifacts stay firm from one day to the next, anchoring that person's character over time."
I have read reports that latent schizophrenia is often revealed when people travel abroad. Maybe if your environment and surroundings change drastically, your mind loses its sense of "self" that was based around anchors to the rest of the environment.
This journal article touches on this:
"Long distance travel has long been known to aggravate pre-existing psychosis.... Travel can be a destabilizing life event7 with many potential hazards to mental health, from the effects of drugs used for prophylaxis against infection, to homesickness, to disrupted circadian rhythms, to culture shock."
