Near-death experiences are tricks of the mind triggered by an overload of carbon dioxide in the bloodstream, a new study suggests.

There are many famous people in Hollywood who have had near death experiences. Most of them describe a white light, some of them hear a voice saying something along the lines of "it's not your time, you must go back". One thing they all have in common was their intense desire to go to the presence that was denying them. Some famous Hollywood celebrities have had these experiences more than once. Some of the interesting ones are below:

Peter Sellers: After suffering eight heart attacks, Sellers was pronounced dead. Sellers reportedly saw a loving, bright white light, but then looked down at the operating table where he saw a doctor trying to resuscitate him. He heard a voice which told him that it wasn't his time and he returned back to his body.

Elizabeth Taylor: When Elizabeth Taylor was clinically dead during complications from surgery, she described her out of body experience as going through a tunnel, then to a bright light where she saw her deceased husband. She claimed that her husband told her that it wasn't her time.

Louis Gossett, Jr.: Gossett has reportedly had five near-death experiences. He saw a past incarnation of himself as a pirate off of Morocco, and a tunnel of light.

George Lucas: After being involved in a car crash before graduating from high school, he discovered that he had a purpose and has been spending the rest of his life trying to fulfill it.
