The terms afterlife or life after eath refer to the continuation of existence of the soul, spirit or mind of a human (or animal) after physical death, sometimes in a spiritual or ghostlike afterworld. Deceased persons are usually believed to go to a specific region or plane of existence in the next life, often depending on the rightness of their actions during life. Some believe the afterlife can be another life in this world (reincarnation). The major views on the afterlife derive from religion, esotericism and metaphysics. There are those who are skeptical of the existence of the afterlife, or believe that it is absolutely impossible, such as the materialist-reductionists, who state that the topic is supernatural, therefore does not really exist or is unknowable.
