My unstable uncle showed up in my parents' living room. He was shorter than normal.
Dreams are highly subjective and can have different interpretations based on the personal experiences and emotions of the dreamer. However, generally speaking, the presence of an unstable uncle in your dream may represent a feeling of uncertainty or instability in your waking life. The fact that your uncle appears shorter than normal might be a sign that he has less power or influence than you originally thought or remembered. This may symbolize your desire for him to be less imposing or intimidating in your life. Alternatively, the dream may simply reflect your feelings towards your uncle as someone who has been unpredictable or sporadic in his behavior.
