Different dreams mean different things, SPM. They are produced by the subconscious mind, and express the thoughts, experiences and feelings of the dreamer. Lots of dreams, maybe most, merely reflect the random sorting of thoughts and feelings that the subconscious mind does every night while the conscious (waking) mind rests in sleep. These dreams have no particular meaning, but are just random images. Other dreams use symbols and metaphors to express the dreamer's deep emotions, fears, hopes, grief and urges.
Here is a link to the FAQ page of a website with lots more information and examples of dreams and what they mean.
