Sam's advanced language skills surprise his parents. He mentions having a sister who turned into a fish due to "bad guys," which eerily aligns with the grandfather's sister's murder decades ago. One year before Sam was born, his grandfather had died of a cerebral hemorrhage.

• Hinduism: The concept of reincarnation is central to Hinduism. The belief is that the soul (atman) is immortal and continues to be reborn (samsara) into a new body after death, depending on its karma (actions and deeds). The goal of Hinduism is to achieve moksha, or liberation from the cycle of reincarnation.

• Buddhism: Buddhism also teaches the concept of reincarnation, but with some key differences from Hinduism. In Buddhism, the soul is not immortal, but rather a temporary construct that arises from the mind.

Nirvana in Buddhism is the state of liberation from suffering, desires, and the cycle of rebirth. It represents perfect peace and enlightenment achieved by letting go of attachments and understanding reality.

• Sikhism: Sikhism believes in "Punarjanam," the cycle of birth, death, and rebirth. The goal is to attain spiritual liberation and merge with the divine and break free from this cycle. Guru Granth Sahib, touches this concept well

• Jainism: Jainism teaches "Samsara," the cycle of birth and rebirth due to karma. The aim is to achieve "Moksha" by purifying karma through non-violence, truthfulness, and detachment, as outlined in the Jain scriptures which resembles the core concepts of Hinduism and Buddhism.

Ancient Egyptian religion, Taoism, Tibetan Buddhism etc also support the concept of reincarnation as well. We'll briefly discuss about these all and will try to cover as much as possible in future. So stay tuned..

Many Americans, including Christians (29%) believe in reincarnation, with a significant number even recalling their past lives. The Dr. Oz Show has featured proponents like Dr. Tucker and Dr. Eben Alexander, while reality TV series including "Life, Death and Reincarnation", "The Ghost Inside My Child" and "Who Was I: My Past Lives" explore cases of past-life memory. This fascination with reincarnation stems from its hopeful promise of improving in subsequent lives, offering an alternative to the concept of eternal hell. This belief provides a sense of mercy and opportunity for personal growth.

Many famous intellectuals and writers in the Western world have expressed belief in reincarnation. Thomas Edison mentioned starting a new Earth cycle, while Henry Ford adopted reincarnation at 26, finding it a way to utilize collected experience across lifetimes, easing his mind and expanding his perspective on time. This indicates a notable historical interest in the concept of reincarnation.

One of the UVA case studies involves a young Oklahoma boy named Ryan who experienced vivid memories of a previous life. At the age of four, he expressed a strong desire to return to his former Hollywood home, describing it as glamorous with a big house, pool, and fast cars. He would often express being homesick and frustrated by his inability to remember all the details. When his mother, Cyndi, showed him old Hollywood books, Ryan became excited upon seeing a picture from a 1932 movie, "Night After Night" identifying one of the actors as himself in his previous life.

Dr. Tucker learned about a notable reincarnation case from TV producers in 2002. This case involved James Leininger, a Louisiana boy who believed he was a World War II pilot shot down over Iwo Jima. The Leiningers discovered James' memories when he was two, recounting a plane crash nightmare with specific details. James also knew intricate WWII aircraft details that seemed beyond his age. For instance, he accurately corrected his mother about a plane's components and identified aircraft names in a History Channel documentary.

The boy named James Leininger claimed to remember his past life as a WWII pilot named James who flew off a ship called the USS Natoma. The Leiningers found a WWII aircraft carrier with the same name and a pilot named James Huston who died in action. James had nightmares about his plane crashing, but his distress lessened when his mother sought help from a past-life therapist. James's parents wrote a book called "Soul Survivor" about their experience.

Skeptic Professor French suggests James' memories could be influenced unintentionally by parents and circumstances. Dr. Tucker claims documentation supporting James's statements predates any knowledge of James Huston, while French argues that children's statements can be ambiguous.

In conclusion, the phenomenon of reincarnation has captured human interest through compelling case studies. While skeptics question the origins of past-life memories, proponents present intriguing evidence, as seen in cases like James Leininger's, Sam and Ryan. The exploration of reincarnation prompts contemplation about memory, consciousness, and the possibilities of existence beyond a single lifetime, bridging the gap between the known and the enigmatic. It's up to you either you want to believe it or not.
