The dreamer’s subconscious is using the setting of a buffet style diner to represent the many choices and options in their life. The pizza symbolizes indulgence and satisfaction, suggesting that the dreamer may be feeling overwhelmed with choices and seeking comfort. The appearance of the former friend from college with a wig on could represent a feeling of betrayal or deception. The fact that the wig is expensive and high quality could suggest that the dreamer feels that this person is putting on a facade or trying to impress others. The wig also being of a different style and race could symbolize the dreamer feeling like this person is not being true to themselves or trying to fit in with a different group. Overall, this dream may be reflecting the dreamer’s feelings of uncertainty and discomfort with the choices and people in their life.
