Scientists in the US have an interesting new theory on what happens after we die.
Researchers at New York University's Langone School of Medicine claim the mind continues to be aware of what's happening, even when the body has stopped showing any signs of life.
Theoretically, this means we may be able to hear our time of death being announced by doctors.
The researchers, led by Dr Sam Parnia, have been studying people who technically died after suffering a heart attack - but were later revived.
Speaking to Live Science, Dr Parnia said some of those involved in the study were aware of full conversations going on around them after their heart had stopped and they were pronounced dead.
Their accounts of those conversations were then verified by the nursing staff who were present.
