Interesting question and raises the issue of what manifestations are in different dimensions. In dreams, the REM state, rapid eye movement is an electromagnetic manifestation of changes in the synaptic connection of nerve cells. As such, the slow-wave, alpha-like states and excitations in the nerve endings "manifest" subjective imagery and consciousness in the dream state, possibly recalled later, as a "phenomenological" manifestation as juxtaposed to an objective "concrete" observer reality dimension. As such, these dimensions overlap yet retain their distinctive properties. Dream a little dream often enough and it could become transformed into concrete observable reality.

Dream remains with us as a part of our activities, Knowledge & Interest . It is in this line some years back I have expressed my views in my answer which I submit herewith for your information

For every person generally our mind does not require to prefer silent  as with the play of five elements ,is mind gets tuning with the conscious mind & if it has a visionary aspect turning to the tune of higher self ,he receives the cordial support of his conscious mind .

Our desire attachment ,emotional phase become a major part of our action in our mind .Psychological comes at this stages where thru the psychic process that is of our mind dream virtually start in our mind .This dreaming process may work generally as a visionary process & it may not offer the helping hand to the dreamer .

When we talk regarding the Psy function we are interested in our dreaming part which gives & also offer us a guiding factor of our mind so that if necessary we may take the help of such dreaming experience of our life in right spirit .

The function of Psy as a process a dream part must have a tuning within the divinity within us & for which we have also to carry out the process of our mind in a scientific spiritual mode .Our dreaming process must have a guiding & energetic force so that our dream should not remain as a visual experience.

This is my personal opinion

Thank you so much for your valuable observations Rohit Manilal Parikh and Don J Feeney .

It might be helpful to add that the totality of human consciousness has inherent within intuitive, wholistic dimensions aware of one's moment-to-moment needs, intentions, and purposefulness. Such wholistic, intuitive alertness could encompass both conscious and deep unconsciousness dimensions such that the vast range of information and interrelatedness is beyond the scope of daily conscious thinking and verbal expression. As a consequence, the imaginative, symbolic subtle nuances of meaning are enfolded within the dream and dream-like manifestation serving to mitigate emergent needs and agendas of each person's present-oriented experienced reality. Thus, hypnogogic, dream states are a means whereby the vast complexity of the individual's present life condition/reality and whatever here and now issues are emerging, vastly more complex than one's conscious mind could process, are integrated and symbolically manifesting alternative pathways of resolution for reflection and processing when one re-enters awakening of their conscious mind. Dream journaling and preparing before sleep what is reflected upon just before sleep serves to orient our unconscious, intuitive symbolic dream states to mitigate and suggest alternatives for more relevant, immediate organic enhancements in our sense of purposefulness.

Yes. I am totally agree with your perspectives Don J Feeney but for example, if someone is hungry in dream and in waking he is already taken his food before sleeping, then what would be the perspective about starving during dream? Is it only illusion or indicating some related understanding which is designated by some hidden clues?

What do you think about this structure?

Greetings, and very good question! Reminds me of the old adage, "MAN OR WOMAN DOES NOT LIVE BY BREAD ALONE"! Food, like any other commodity, may be experienced literally as an actual slice of bread and/or symbolically as that quality which nurtures and "feeds" the soul so to speak as in quality time and attention on one's self and/or others. The "hunger" for loving relationships or meaning in one's lifestyle or some other dimensional human quality may be emerging but as yet unidentified as the dream of eating one's hunger defies logic as a paradox yet symbolizes that we're still missing the "right stuff" of what fulfills us! The dream is a "Gift" in that the discrepancy of unsatisfied fulfillments challenges us to probe and explore that which is truly essential and at the heart of what reveals the nature of our Being! Ironically, the dream is an "Awakening" from the daily "delusion" of "mindlessness" about the phenominal Being we truly are!

Thanks for your consideration. I agree with your statements but do you not think that now time has come to determine the dreaming truth without any waking world boundary? because each and every discussion is always judged by waking state perspective like in waking seeing 'Apple' is real because of physical visibility but if someone sees a new object first time in his or her dream then that object is only real because of the lack of 'waking permission'. Do you think this is right attitude? because we get different solutions from dream and these are helpful to get rid of waking problems. Can we say the new object of dream is unreal? maybe forms are different not like waking state.

What do you think?

This is an intriguing question: whether seeing an object for the first time in a dream, is it only "real" because of the lack of 'waking permission'? If by that question, you mean the newly dreamed object (eg: PURPLE APPLE) has not been seen nor verified in the person's awake state, in my understanding It's real to the dreamer in their subjective, phenomenal reality. Whether that person wakes up and does not see or find "Purple Apples" in concrete reality doesn't mean it isn't Virtually "Real" for the dreamer in their altered consciousness of their dream state of mindfulness. You may benefit if you realize that "what's real" depends on how you define reality as a dimensional construct. The awakened state of consciousness is one defined state of set realities and could be contrasted or juxtaposed to the dream state of consciousness of highly creative, symbolic morphic formative expressions affected by the unique subjective personal thoughts, emotions, and senses of one's mind-body experiential condition.

It seems more accurate to note that there are differential states of reality rather than to suggest that one state is more "real" or "unreal" than the other. There is of course, interfacing of these realities, and what happens in one reality could influence the other. Dreams could be the person's inner reality reinterpreting and consolidating one's outer physical reality experiences. Hope this is helpful.

This is really good observation Sir. I agree with you. I actually would like to focus on this logical possibility like ' PURPLE APPLE' . ' PURPLE APPLE' indicates some incidents or issues regarding waking state.

So, sometimes dreaming state can lead the waking state. We can think sometimes in this way.
