Below is an article regarding scientific research on the possibility of links between obe's and lucid dreaming. This article explores similarities between lucid dreaming and some aspects of obe's. I read the entire article, and it is the sort of information most people will likely be hearing from the scientific community.
Otherwise, one might hear the kind of "horrific" stories of hell, such as what was broadcast a few nights ago where I live. This description of "hell" from a near death survivor was given with very little context. If anything, it would do nothing but inspire fear in others who happened to listen.
How have those of you who have experienced obe's resolved your own questions about your experiences, if you have? What is it about your experiences that does or does not convince you that these are real, actual, "out of body" experiences?
This post is not meant to question individual experiences as much as to encourage continuation of efforts in these directions. I am interested in how you have resolved your own doubts, if you have had any? 
All thoughts welcome.

OTHER WORLDS: OUT-OF-BODY EXPERIENCES AND LUCID DREAMS
by Lynne Levitan and Stephen LaBerge, Ph.D.
========================================================================
"Out of body" experiences (OBEs) are personal experiences 
during which people feel as if they are perceiving the physical 
world from a location outside of their physical bodies. At least 
5 and perhaps as many as 35 of every 100 people have had an OBE 
at least once in their lives (Blackmore, 1982). OBEs are highly 
arousing; they can be either deeply disturbing or profoundly 
moving. Understanding the nature of this widespread and potent 
experience would no doubt help us better understand the 
experience of being alive and human.
The simplest explanation is that OBEs are exactly what they 
seem: the human consciousness separating from the human body and 
traveling in a discorporate form in the physical world. Another 
idea is that they are hallucinations, but this requires an 
explanation of why so many people have the same delusion. Some of 
our experiments have led us to consider the OBE as a natural 
phenomenon arising out of normal brain processes. Thus, we 
believe that the OBE is a mental event that happens to healthy 
people. In support of this, psychologists Gabbard and Twemlow 
(1984) have concluded from surveys and psychological tests that 
the typical OBE experient is "a close approximation of the 
'average healthy American.'" (p. 40)
Our conception, also proposed by the English psychologist 
Susan Blackmore, is that an OBE begins when a person loses 
contact with sensory input from the body while remaining 
conscious (Blackmore, 1988; LaBerge - Lucidity Letter; Levitan - 
Lucidity Letter). The person retains the feeling of having a 
body, but that feeling is no longer derived from data provided by 
the senses. The "out-of-body" person also perceives a world that 
resembles the world he or she generally inhabits while awake, but 
this perception does not come from the senses either. The vivid 
body and world of the OBE is made possible by our brain's 
marvelous ability to create fully convincing images of the world, 
even in the absence of sensory information. This process is 
witnessed by each of us every night in our dreams. Indeed, all 
dreams could be called OBEs in that in them we experience events 
and places quite apart from the real location and activity of our 
bodies.
