Wave,
You don't have to be in other than conscious state when PRing. You can be fully conscious, no problem. All that is required, you relax your body, and your eyes. That's all. Mastermind has above explained two methods to do this.
Good indicators of the right PR state ar the blip page, peripheral vision widening, slow breathing (not too slow!), shoulders moving a bit downwards, self-talk (mind chatter) quieting down, a sort of calm feeling... etc.
Maybe you don't notice yoy going to the right PR "state" is because you are not yet accustomed to notice it? It's nothing fancy, you may be several times a day in that precise state naturally!! Actually, I think that being in the this relaxed state is essential for everybody's well-being, otherwise you tend to get nervous and stressed... But, Good luck! -purjo
