Example: A woman dreamed of feeling forced to sit on a hot pipe by a “disease demon.” In waking life she was experiencing anxiety about taking time off work to deal with painful inflammation she was feeling in her bladder. The hot pipe may have reflected her feelings of putting up with the pain of her bladder inflammation in order to keep her responsibilities at work running smoothly.
Example 2: A young man dreamed of using a pipe as a weapon. In waking life he felt the need to defend himself against an overbearing father who was trying to control his life.
