@X: That's a relief to know. Yeah I have heard about the silver cord, but some people say it can be cut not just by death alone.
@zangetsu: I lucid dream all the time.
I've flown across the earth in a matter of minutes, once in a dream. It started out as a regular flying dream that moved up to outer space. I loved that dream. But most of the time, whenever I encounter flying dreams (they have become rarer these days), there is some sort of invisible ceiling that prevents me from going up further than a helicopter's point of view.
I also have dreams of the distant past (recently they have become rarer too), sometimes speaking in languages I do not know, in a body that is not my own.
Explanation, anyone?
