Faceless
To dream of a faceless person represents an aspect of your personality that is undefined or undecided. Beliefs or wishes that keep changing, going in new directions, or never stay the same. You are having trouble knowing what you want or making a final decisions.
Alternatively, a faceless person may reflect your feelings about an unknown future situation. Not knowing what to expect.
Example: A woman dreamed of having sex with a faceless lover. In real life she was enjoying being single and trying new things. She felt a sense of freedom in not knowing what she really wanted in life.
Example 2: A woman dreamed of seeing a faceless man. In waking life she was pregnant by a man she didn't know that well and was nervous about whether or not he would be a good father.
