An increasing number of people today believe they have had an experience of coming back from death. They describe death as being very pleasant.
Death is like a very deep sleep.
There are no thoughts or emotions, and without thoughts or emotions there can be no consciousness. In death you are asleep in the grave, without knowledge, without emotions, and without consciousness. The people who think they have died and come back were not really dead. Death is not the end, however. There is to be a resurrection from death.
