my dads friend died for five minutes in hospital, and he said nothing happened while he was dead, and a few weeks after he came back to life, he attempted suicide, because he knew there was no 'afterlife', then when he came back to life the second time, he said he had a strange dream, and obviously he started to think there was an afterlife after all, now he doesnt complicate his life with silly little things, he simply lives life to the fullest, he even started smoking weed
