Dreams about personal appearance, especially in relation to beauty and body modifications like piercings, often reflect how you perceive yourself and your identity. The act of taking out your piercings could symbolize a desire for change or a need to reassess aspects of your identity. It might suggest that you are in a phase of self-discovery or transformation, considering how you present yourself to the world.

The imagery of looking more beautiful than you perceive yourself in waking life might indicate a longing for self-acceptance or a deeper appreciation for your own beauty. The additional piercings could represent feelings of individuality or a desire to express yourself more boldly.

The graphic nature of the injury you experienced in the dream, despite it not being painful, could signify underlying fears or anxieties about vulnerability or change. The slicing of your cheek may symbolize a fear of losing parts of yourself or feeling exposed in some way. It can also suggest that you might be struggling with how others perceive you, or how you perceive changes in your life that you feel might be damaging or risky.

Running to your mom for help indicates a longing for support and comfort during times of distress. It could suggest that you are seeking reassurance in your waking life, especially when facing challenges or changes.

Overall, this dream seems to reflect a mix of self-exploration, concerns about identity and vulnerability, and a need for support. It may be beneficial to take some time to reflect on any changes or feelings you are currently experiencing in your life, and consider reaching out to loved ones for support as you navigate these feelings.
