tibetan dream yoga helped me some with this
you ask yourself during : the day am i awake? or dreaming?
and a few other things like that
before sleep you say a kindo of mantra (English so it does not have the power of Sanskrit or Hebrew)
and sleep on the right side for male left for female
u write down it in the morning
it is a great practice which i am getting into quite a bit
good luck with whatever you do
