How can we fall into our dream? We get the last images passing through our mind, different pieces of problems and things seen during the day.
At the beginning they have no sense, then, little by little, we put them together with strange links... A new story starts, a tremendous interesting story about us... So we are in the dream.
That's the way I used to help the patiens of the new part of the Ruhrland-Klinik in Essen for the 'Sleep Apnea' to fall into their dreams.
I've got 'nearly' all the pieces of the pictures from people and things nearby.
