Example: A woman dreamed of being in a castle. In waking life she was recovering in the hospital and felt that all her friends and family were giving her "royal treatment" while she recovered.
Example 2: A man dreamed of being inside someone else's castle. In waking life he was annoyed by family members whom he thought were too controlling and domineering.
Example 3: A young girl dreamed of being led out of a castle by a friend. In waking life the dreamer realized that she was too introverted and defensive about it. A friend helped to tone down her defensive nature.
Example 4: A wealthy woman dreamed of being imprisoned inside a castle. Shortly after the dreamed occurred she contracted the "sleeping sickness" and her entire life was ruined.
