Rubber
To see rubber in your dream represents
adaptability and versatility.
Negatively, it may reflect issues that have a tendency to reverse or bounce back. You may be dealing with sensitive issues or problems that you're able to handle, but occasionally come back and bother you.
Rubber Band
To see or use a rubber band in your dream, represents your accommodation to others needs or wishes, or their accommodation to yours. You are possibly feeling like you have no choice, but to do assist or help others while ignoring your own interests.
The color of a rubber band is significant. A red or black band would hint at imbalanced or negative thoughts and feelings about this accommodation. A blue band would be suggesting the accommodating attitude is positive.
