I've recently read LaBerge's book about Lucid Dreaming, but one thing he claimed made me sceptical...

How can gravity-related problems such as learning how to do a specific trick in freestyle, be learnable in lucid dreams? Do you unconsiously calculate the values and estimate your flying orbit through the air using formulas like W=mv2/2 and W=mgh. No I dont think so...

So how come you actually learn how to perform a skill if you don't have any frames of references at all? Let say you have never done a backflip in your life... ?

How can you get better in real life by practicing a gravity-related trick in a lucid dream?

Or am I just holding the wrong end of the stick?

thanks for your help
