The first, and most important rule of dream interpretation is to always remember that symbols may have different personal meanings for different individuals.
The importance of a dream is usually in direct proportion to the impression it makes on the dreamer.
Dreams that generally have little or no prophetic value are those that: Occur during the first few hours of sleep; Concern a person or event recently spoken of; Result from external stimuli, such as a book just read or a film or television show just watched; Result from illness, especially if medication is taken.

According to Ibn Sirin, one of the first writers on dreams, if one wishes to have a prophetic dream then , "The sleeper, lying on the right side, will have abstained from all excess of food or of drink. He will have gone to sleep with a light heart, an easy conscience."

Rule of opposites: there is a well-recognized rule of opposites in dreams; thus, dreaming of death often means a rebirth of some sort, such as marriage or the start of a new career.
This same rule is operative in interpretation of the Tarot, and in many other symbol-systems as well. One explanation of this phenomenon is that the subconscious does not deal with opposites in the same manner as the conscious mind. Thus, "heads" is not the opposite of "tails;" either is related to the other, and so can be used to call to mind the other. As a side note, there is mention of this need to "twist round" what happens in a dream to get at its meaning in an obscure song called My Dream Blues, which was recorded by "Black Bottom" McPhail in the 1930's.
