Questions to ask yourself
To interpret your dreams properly, you should ask yourself the following questions.
When was the last time this element appeared in your waking life? In which context?
Dreams often incorporate recent elements of our waking life. If you’ve seen this element in a movie recently, for instance, it may explain the presence of this element in your dream.
What does this element represent for you? Could it be a metaphor for something else?
During dreams, your mind makes a lot of associations between concepts. An animal may represent a person, a person may represent a period of your life, etc... Think outside the box; what could this element represent?
What emotions does this make you feel? Did you feel those emotions in your dream?
Were you surprised to feel unexpected love or anger towards this element? Think about why you may have felt those emotions.
What else was inside your dream?
Think about the other elements of your dream and their relation with this specific element. Then, you can start this process again with these other elements.
