I met an neurologist, and he said that dream is some kind of reorganisation of memory, some kind of difragmenation. This activity of optimisation of memory space create an electric activity, this electric activity is "recognised" by consciosness, and this recognition of electric activity show us different mixed images of our live.
I always say that DREAM IS NOT SELF, there is no any message, of mystic, or magir, or god acivity; NO. It's just a dream, absolutely anatta.
That is concerned the question of this topic:
WHO(what) IS HEARING? WHO(what) SEE DREAM?
It's much more important to know...
Sabbe dhamma anatta
We are not concurents...
