Generally speaking, the longer someone is clinically dead before being resuscitated, the more intense their experience. But there are also numerous examples of people who have had intense experiences over a very short time. There's not a definite correlation between the two.
一般而言，臨床死亡（如已宣告腦死）較久後再甦醒的人，其經驗會比較深入，但也有不少經歷時間短、體驗卻非常深入的案例，兩者沒有絕對關聯。
