Just a heads up this post contains spoilerish stuffs sooo just to warn ya. If you don't want it spoiled turn back. What has been cannot be unseen XD.
Anyway, I've been doing some thinking. Other than Vengeful Ghosts, and failed rituals there is another constant force in the Fatal Frame series. A family to be exact, and descendants of that family.
Miku Hinasaki, the main protagonist's mother was Yae Kurosawa's daughter. The same Yae Kurosawa that that ran away with Ryozo Munakata in Fatal Frame 2, and settled in Himuro Mansion.
Fatal Frame 3 has a Kurosawa family member as well, but is Rei a descendant of Yae as well? Did Yae and Ryozo have more than one child? I kind of forgot :/. That would explain then how Rei and Miku met, and lived together. They could very well be half sisters. That could also in a way explain the car crash too since the Kurosawa family seem to be especially sensitive, and susceptible to spirits. It was also raining too, and water is said to be a doorway into the Spirit realm.
In the first cutscene in the ruined Manor or Sleep, Miku seemed pretty eager to leave (She probably knew what was up), and Rei got led into the manor by her deceased Lover, Yuu. A man whom knows Kei Amakura, the uncle of Mio, and Mayu. Twins who got lost in All God's Village. The Kurosawa's ancestral home.
In Fatal Frame 4 I really didn't know of any links to Kurosawa. I haven't played the fourth game, so if anyone could shed some light that would be most helpful.
With 5 Miku returns, and she has a daughter this time. Both get captured by spirits, and must be rescued.
What do you guys think? Do you think the Kurosawas are a part of the same family? Is there a possible link?
Would love to see your theories too .
