"In the period immediately after death, the spirit-soul remains close to this world, observing how the family is doing, going out to visit friends at their home, or going to worship at a shrine or Buddhist temple. Many are not yet clearly aware of their own death status. Some still retain a part of nigimitama, so they have a semi-material body and can even make noises. Those who have psychic powers are able to see them. Usually they spend a certain period of time, the so-called “forty-nine days,” in such circumstances. In Buddhism they call this circumstance chuyu, meaning “existing in the middle.” A while afterwards they become aware of their death and fully move onto the other world, or yukai."
