Your mind is of more than one level. Some of its workings are apparent to you, like your concious thoughts and feelings, however even your concious thinking has a unconcious basis to it. Meaning we have certain prejuduces in much of our thinking, in accordance to how our internal carvings have been made. Expereince imprints itself upon our mind in the form of images (imagos, Complexes) that have feelings and certain significance to us. These images are usually unconcious and we usually can’t see them, unless sometimes when they are provoked from outside sources, such as a certain event that we have somehow associated with a past expereince that has been saved in a certain image.
Now to make a very long story short, when we fall asleep our logical brain falls asleep, and this is partly why we have weird and illogical dreams with irrational dicision making. however this is not the full story, because sometimes our logic remains intact. The issue is that it apears that in most cases our subconcious part begins to surface upwards and show itself. Our concious ego, which controls and limits the freedom of expression of our whole psyche during our waking hours becomes less active and so our pysche begines to pose to us questions and problems that we are usually unaware of. These things may come in forms of nightmares and such, but they have been seen in many of the cases to be helpful and pinpointing our issues and insuring our freedom from the things that we usually seem to have no control over. Again long story short there is great evidence that dreams are helpful and serve a great rule in our awakening from our ignorance of our selves and the environment and people that surround us. Our Subconciouness is much more truthful then we are…
Now to your main question. We cannot know the significance of your dream to your personal life, unless we were to analyse some of your thoughts, like by using the word association test and so forth. You must know what the symbols in your dream represent, and you must be careful because your ego has a shadow and a persona, hence the persona being how you present yourself to your environment and your shadow your presentation of your hidden likes and dislikes. Sometimes the shadow presents itself in a dream as being someone else. like a dream character, and you will doubt it is you, but to an extent it can be your shadow…
