Okay looks like I have to chime in here.
Dreams are complicated. They are, in mundane essence, the subconscious mind attempting to resolve emotional conflicts and confusions that were left open in the conscious mind. Reoccurring dreams are often found in people with cyclic emotional patterns. Pleasant dreams usually are just the expression or anxiety towards a hope. They are primarily designed to sort the unsorted emotional content. Your brain tries to do this subconsciously during most of the day. However the requirements of conscious thought inhibit this during day to day activity. The greater of a balance you have between you abstract and cognitive thought the less likely you are to recall or even have real dreams.
Now for the other side of it. Dreams can in fact be interpreted by someone with the proper ability to draw the lines between symbols and definitions. They can even in some positions be used to see forward slightly. This is usually due more to the dreamers intuition than the interpretors own insight.
I agree with the former, but not entirely the latter. Here are my thoughts on dreams. Dreams
can be interpreted, as in the case of Joseph and Pharaoh in the Christian Bible. However, not all dreams are meant to be interpreted. Probably about 99.9% of all dreams one will remember will only be one's subconscious sorting emotions, thoughts, and memories and trying to make one's next day start off on the right foot, so to speak. Also, things one experiences during a dream, such as extreme heat or the sound of music playing, can often influence a dream.
