Really?
Is that true?
I've never heard that.
Is that true?
I've never heard that.
I don't have a reference document or link to which to refer you because I remember reading about it years ago in a psych book but that is what this book said.
I have no idea whether or not it is true. However, if you stop and think about it what happens when you awaken from a dream about falling? My heart always races so I would have to give some credibility to the idea.
