Dreams often reflect our subconscious thoughts, feelings, and fears. In your dream, the bathroom may symbolize a private space where you confront personal issues or emotions. The child with black hair and eyes could represent a part of yourself or a situation that feels threatening or unsettling. Children in dreams often symbolize innocence or vulnerability, but your experience with this child is quite the opposite, suggesting that you may be grappling with feelings of fear or anxiety in your waking life.
The fact that you tried to keep the child at bay while also feeling overwhelmed hints at a struggle between wanting to protect yourself and feeling powerless in a situation. The broken glass could represent a loss of control or the shattering of safety, while the act of screaming for help signifies a desire for support or a need to express your distress.
This dream might be prompting you to reflect on areas of your life that feel threatening or out of control. It could also indicate unresolved emotions or conflicts that need to be addressed. Consider what in your waking life might be causing you fear or anxiety, and think about ways to confront those feelings constructively. Seeking support from loved ones or a professional could also be beneficial if you're feeling overwhelmed.
