Sanzu no Kawa
It is the dividing line between life and death. Dead people passing through the Sanzu no Kawa will dream about what happened in the past and in the future. This dream will show your inner feelings of expectation, anger, helplessness and despair. So this dream also determines the cause and result of what you do in your life.
