Dreaming the munchies

This is just a crazy theory that I have been thinking about one morning after waking up from a suffered dream in which I was hungry and trying to feed myself. Nicely enough when you're hungry in dreams you also find yourself next to the best options you could have in real life, like 5stars hotel buffet or all you can eat places, restaurants and so on.. all happy and satisfied because you're going to suppress the hunger feeling that you are perceiving in the dream. Often after waking up from those dreams, you still feel hungry and in need of food. This makes me hypothesize that we can dream what we feel, if the feeling is strong enough. I have been looking for research papers on dreams, however I didn’t find anything yet where particular emotions / perceptions are discussed in relation to what subject remember to have dreamed. I may understand that the research data could be discussed as non-valid because subject could be biased by the nature of the research and could add personal touch and feelings to what they really remember of their dreams --> asking someone to recall a dream focusing on the emotions, body sensations, could bias what the subjects recall from their dreams. One option could be to wake up the subjects during REM activity and ask them to write down what they recall without thinking too much about it as brief awareness = unconscious mind response.
I am really interested in emotions like fear, despair and such negative emotions as I always believed that the representation of those in dreams are just the representation of feeling we are bearing inside (overt or covert) and we suppress with our conscious mind. Unconscious mind wakes at night when the conscious mind is less responsive and fires the same info to the brain.
Studies on the content of dreams are very difficult because they rely on what the subject recalls, I will still look around for research papers to add to this post. This is merely a little hypothesis, based on the fact that hunger is present as a sensation and feeling in dreams that many people recall to have. Another way to approach the subject could be asking: is the hunger we dream of real hunger?
It's a couple of days that I have been thinking about emotions and feelings represented in dreams and how these could be scientifically studied, however I could not find anything scientific to back this up or relate this to (yet). - TO BE CONTINUED -
