Brush
To see a brush in your dream symbolizes your desire to "brush" away problems or something in your life that needs to be cleaned up. Perhaps you are taking a nonchalant attitude toward circumstances that need serious consideration.
If you lose or can't find your brush, then it suggests that you are unable to sort out your problems.
To dream that you are brushing your hair suggests your need to organize and sort your thoughts. You need to search for some elements that are not clear. Brushing your hair may also highlight your preoccupation with appearances and beauty over substance and quality.
Dreaming of brushing your teeth suggests that you are feeling defensive about any criticism directed at you. You are putting up a shield or barrier to protect yourself from potential harm. Alternatively, the dream means that you are preoccupied with your appearance and are worried about how others perceive you.
To dream that you don't want to brush your teeth implies that you tend to speak your mind, even if it may offend others.
