I too kept a dream diary for many years. I cannot remember whether I described my own classification of them here. For what it's worth, my own dreams fall into three types.
1. Vaguely unpleasant ones, usually involving at least one sequence about grimy lavatories and all matters connected with them, the details of which are thankfully too obvious to go into detail about. These, I have proved, have their origins principally in digestive and other bodily disturbances. Enough said.
2. By far the largest category, wherein the unconscious is, through symbolism and association of every imaginable type, visually thrusting an issue, situation, problem or opportunity at me, which my conscious mind has not realised but which is glaringly obvious to my unconscious mind. These are the classic dreams of the psychologist and , as Jung rightly said, to ignore them is like leaving unopened a letter addressed to oneself. Although innumerable texts on their interpretation exist, from learned psychiatric journals to the pages of the Woman's Weekly, it is my opinion that I am the best person to analyse my own dreams of this type.
In many cases, doing so has saved me considerable upset and bother, not in any precognitive sense, but through highlighting a possible outcome of some life event or decision. A typical case was a dream about a catastrophic computer failure at work, with certain characters appearing on a screen preceeding the crash. The next day, somewhat relieved to find things working, I saved all files and programmes just in case. The day after that, the characters suddenly appeared on my terminal and the system crashed completely, necessitating a disk replacement and complete restore. There was no magic in this. Working with a computer all day, my unconscious probably absorbed normal patterns of activity, on screen and elsewhere. Most likely these patterns changed, but not enough for my conscious brain, however conscientious, to register the fact. My unconscious, however, knew all - the characters to look for (which I had probably read in a manual and forgotten), the general pattern of activity and the fact that the most recent complete save was not adequate. It then couched the lot in the form of a very dramatic dream I could not ignore.
3. The visionary dreams. These, to put it simply, are overwhelmingly beautiful, extraordinary and completely unforgettable. They sometimes, but not necessarily, include "out of the body experiences", lucid dreams (wherein one controls the dream substance at will), "tunnels of light", meeting supernatural beings and all the other commonly described mystical states. I have had these more frequently at certain times of my life than at others. The finest of them have literally shaped my mind for the better and remain a kindly influence simply by thinking about them, even years afterwards. I have a private theory that perhaps all religious experience and myth began with these things. Certainly, I can see how the vivid, "past life" variety, of which I have had many, could imprint on all but the hardiest of rational thinkers a fervent belief in reincarnation. It is a curious fact that, unlike many mystics ( I think it is possible to embed mystical experience in a rational life, but I shan't argue about that here) I have experienced many celestial visions but none at all of hell or even of anything slightly less than the transportingly ecstatic. All my visionary dreams are invariably good and beautiful in the profoundest sense of the words.
Anyway, m1469, to return to your question, I tend to suggest your dream belongs to the second category. It is trying to tell you something, and the best person to analyse the symbolism is you. Remember that dreams love puns and tricks of language. Also, people and objects in the dreams may not represent themselves but facets of your character, thought or situation. Thus dreaming about dear old Auntie Mary dying may not indicate the actual death of Auntie Mary, past or future, but the possibility of your losing some quality she represents to you.
Quite often, leaving aside traumatic experience or other psychological problems, having a recurring dream indicates that you have not yet completely understood its message, at least that's how it sometimes works with me.
