Are Out Of Body Experiences Real?

Out-of-Body Experiences

Out-of-body experiences (O.B.E.), also known as astral projections, are

the event in which the human spirit or soul is believed to exit the body temporarily during a near death experience (N.D.E.) – allowing them to roam freely between separate dimensions. 

Though O.B.E. are not scientifically falsified or proven to occur, there are many who claim these experiences have happened to them and are real. There are even individuals who attempt to astral project from the body regularly through spiritual rituals. 

However, many skeptics believe that O.B.E. are merely illusions caused by head trauma from car accidents or loss of consciousness from other traumatic events. 

Questions

What do you believe? Are out-of-body experiences real or merely illusions from trauma? How can either case be proven to be objectively true under all circumstances?
