Have you ever seen in documentaries, people talking about "out of body experiences" while undergoing surgery? That being, getting out of their physical bodies and going around like ghosts, and later being able to tell the surgeons and nurses what they were doing and talking about while they were supposedly unconscious.
Apparently, there is a technique called Astral Projection for doing that on purpose. And while using it, right before leaving your body, you may feel different kind of reactions, like vibrations, change in temperature, buzzing sounds, change of size, and.... even inflating like a balloon!
Not everyone experiences it the same way though, but I recently saw this video, and while I didn't intend to talk about the topic at first(as many people will likely not believe this kind of thing), can't resist sharing it. I think you guys will find at least interesting the description of the inflation.

An Astral Projection expert talks about his first experience doing this, during his teenage years, and he describes how he felt like inflating as "that girl from the Chocolate Factory film that was popular at the time":.......... http://www.youtube.com/watch?v=TfTkwdySEu0
It's legit, proven over decades of research. I've gotten *sooo close* to actually leaving, but never got there. Apparently, when you're on the "astral plane" you can do whatever you want :/ I'm actually really jealous of those that can do it.
