To see a head in your dream signifies wisdom, intellect, understanding and rationality. It may also represent your accomplishments, self-image, and perception of the world. The dream may also be metaphor to indicate that you are “ahead” in some situation or that you need to get ahead. If you see disembodied heads in your dream, then it implies that you are having difficulty relating to others. You feel that some people are emotionally distant.
To dream that someone is trying to rip your head off suggests that you are not seeing a situation or problem clearly. Perhaps you are refusing to see the truth. You have to confront the situation or the person despite the pain and discomfort you might feel in doing so.
To dream that you have two heads indicate that you need to learn to ask for help and accept assistance. Consider the metaphor “two heads are better than one”. Do not try to do everything yourself.
To dream that your head is particularly heavy or weighing you down means that you are over-thinking or over-analyzing some situation. As a result, you are unable to move forward.
