My parents allowed me to see this crappy documentary for some reason when I was a small child. I was traumatized by it and never again got out of bed without looking back to see if my body was still lying there! Still, every time I get out of bed, the thought occurs to me. So don't let your kids watch it! That is, if you can even get your hands on it, which I strongly doubt!
By the way, the storyline that affected me most was about a guy who entered the hospital with a chest cold, then left his body and encountered evil satanic nurses. Nice. I can't believe I can remember some crappy documentary from 1978 and that it affected me so much.
I think this movie contributed to an extreme fear of death in me from a young age, and I'd have been vastly better off never having seen it. I am no longer as impressionable of course, in fact I'm a callous skeptic, but I cannot erase the emotional damage caused by this stupid 70's documentary. Lame, I know.
