SPIRITUAL MEANING:
An obelisk is often representative of a Sacred Stone, a marker outlining a particular area such as a sacred space, helping us to be clear regarding our spiritual beliefs or marking a particularly sacred area within which it is safe to practise our spiritual beliefs.PSYCHOLOGICAL / EMOTIONAL PERSPECTIVE:
An obelisk is a man-made needle-shaped stone, larger at the bottom than the top. It is usually taken today to indicate old instinctive knowledge - man reaching for the unknown. In dreams it suggests just that.
EVERYDAY MATERIAL ASPECTS:
Any carved stone appearing in a dream suggests we are considering how we have shaped our own basic nature. The simpler it is, the more room we have for improvement; the more ornate it is, the more successful we are at using our creative energy.
GENDER / SPECIFIC MEANINGS:
Because of its shape, the obelisk obviously has phallic connotations. In both men's and women's dreams it may also represent a hard unforgiving 'core'within the personality.
