I'm not sure but I gather that a person has to have the right energy level going into their sleep to WILD. Too excited and the person will have their mind racing and not go to sleep. To drowsy and then a person will just fall into their sleep and not remember that they've dreamt. So I think that there should be a target medium that needs to be had going into a dream. I have tested different emotional states but not been able to figure out the right "recipe" for me. Things I have tried have included with being positive and trying to build an excess of energy through love, hope, or excitement. I have also tried being passive and just tried to go with the flow of the energy by being attentitive and receptive to good possibilites. Whatever the right balance, I am still trying to find it so that I can enter into a dream with the right energy.
