Twenty Cases Suggestive of Reincarnation is a 1966 book written by psychiatrist Ian Stevenson on claims of spontaneous recall of information about previous lives by young children.

The case usually starts when a small child of two to four years of age begins talking to their parents or siblings of a life they led in another time and place.

The child usually feels a considerable pull back toward the events of the life and he frequently importunes his parents to let them return to the community where they claim that they formerly lived.

If some verification results, members of the two families visit each other and ask the child whether they recognizes places, objects, and people of their supposed previous existence.

[2]Stevenson set up a network of volunteers to find these spontaneous past life recall cases as soon as the children began to speak of them.
