There is a rationale to your dreams, but first you must remember them, to understand them. One technique is using an affirmation like "I will remember my dream tonight" before going to bed.
Deeper meanings can be made from the stories we dream and the symbols we see. Once thought of as messages from the God's, today we understand dreams to be messages and insight inside ourselves.
We can look at a dream as a whole, or as individual symbols and messages through each image you have experienced while asleep. Each image is a representation of a psychological aspect of ourselves.
Dreams can make us question ourselves, who we are and what we're about. The strangeness and unfamiliarity of our dreams may disturb our perceptions of ourselves.
