Hypermnesia

Hypermnesia is the state of having an enhanced memory which usually occurs during atypical conditions like delirium, trauma, or hypnosis. This is in contrast with amnesia which is the loss of memory. Having an abnormally vivid recall has also been reported by those who had near death experiences. For instance, a person who almost died due to drowning claimed that in those few seconds before ultimately losing consciousness, he was reminded of the different events of his life in amazing detail.
