this is an interesting topic, so bascially from what i can sum up from that website,
we enter into a sort of trance after 5-6 hours of initial sleep and we have the capacity to enter into this lucid dreaming. To me it sounds pretty interesting, but im scared of what problems that could be associated with it. On the website it says, that you could still have heartattacks because what you are going through in the dream can affect your physically. (an example of this could be taken from the matrix, if you died in the matrix you could die in reality)
- interesting read *thumbsup*
