Dreams about schools often symbolize learning experiences, personal growth, or feelings of judgment. In your dream, the fact that most people were in matching uniforms suggests a sense of conformity or societal expectations that you may feel pressured by in your waking life. Your feeling of not belonging indicates a struggle with identity or acceptance in a particular situation.

The girl who was upset about her skirt could represent someone in your life who feels constrained by norms or expectations. Her claim that her skirt was a kilt might suggest a desire to redefine or reclaim her identity, possibly pointing to your own feelings about how you express yourself.

Spending your time avoiding attention could signify anxiety about being judged or not fitting in. This dream may be encouraging you to explore your own individuality and consider how you can assert your identity in situations where you feel out of place. Reflect on your current social circles or environments and think about how they align with your sense of self. It might be beneficial to seek out places or groups where you feel more accepted and authentic.
