Hello MM,
While I think that I understand the point you are attempting to make and wish to sincerely thank you for contributing it for discussion in this dream interpretation forum, with due respect I feel that it would have much more meaning and value to other members if you were to in addition to this describe some of the methods by which they could consciously restrict or limit the subject matter of their dreams to a specific area.
This sounds to me very much like what is commonly called
conscious or as leading up to what is known as
lucid dreaming.
See "Exploring the World of Lucid Dreaming" by Stephen LaBerge, Ph.D. & Howard Rheingold 1990 [Ballantine Books]
Especially look at Chapter 4 "Falling Asleep Consciously" as a point to begin your own conscious dream explorations from (pages 79 - 98).
I look forward to comparing notes with you about conscious dreaming techniques, if you are agreeable to doing this.
Yours sincerely,
eye_of_tiger
