A razana (ancestor) might appear to one of his or her descendants in a dream or in a vision, complaining of cold and promising to impart blessings upon the lives of his or her relatives. This is why the Malgasy reopen their family members' tombs and replace the shrouds covering the remains of the dead.
Famadihana, или «переворачивание костей», представляет собой похоронный ритуал, знак уважения своим предкам.
