Well Dream is from s subconcious mind which when goes to sleep is put awake at your thoughts. Perhaps it just reflects the way you think inside yourselves deeper when you have a chance to express it (and usually you dont)
I feel sometimes dreams come to life only when your physical presence expresses what your subconcious minds have thought already and worked it out.

Reality is different completely from your dream and i request the persons to not to waste time on dreams instead be awake to unforeseen problems
