To dream of a car trunk represents issues that aren’t a priority or areas of our lives that are “carried along.” Secondary importance or only doing something when there is a problem.
Example: A woman dreamed of seeing her purse in the car trunk of her fiancee. In waking life she felt that moving into her fiancee’s house was making some areas of her life secondary or less important. She felt that some of her former independence was only important when it became an issue between them.
Example 2: A woman dreamed of looking through her dead father’s belongings in his car truck while feeling pressured to remove them because they may be gone later on. In waking life she felt pressured to record her dreams and bring them to a therapist. She felt that she had better record them now because she might lose interest later on.
