Death is an abrupt transition from life to a new state of matter and consciousness. During this transition, some people experience traveling through a tunnel of light and seeing memories or entities. What is experienced depends on personal beliefs. The physical body loses awareness and the body of light detaches, as seen through special cameras. One's mental and energy makeup, influenced by their actions in life, also affect the transition state. After sojourning in the afterlife, most souls are reborn in new embryos, while some souls' lights remain observable or recall living on other planets in past existences.
