Cutting through a tangle of trees or undergrowth in a dream is part of the Hero's Journey towards spiritual autonomy. He must work hard to overcome chaos in order to succeed. When something like hair is tangled, we need to be aware that our self-image or projection is coming across to other people as distorted, and not how we wish them to see us. Sometimes when we are confused in everyday life, we may dream of an object being entangled with something else. Often the way that we untangle the object indicates action we should take in waking moments. We can cut straight through quickly or patiently work at it.
