To dream that you are being bitten, represents your vulnerability regarding some unresolved issues or emotions. You may be pestered by a problem or obstacle. The dream may also be a metaphor indicating that you have bitten off more than you chew. Perhaps you have too much to handle.

To see a mouse in your dream, indicates fear, meekness, insignificance and a lack of assertiveness. You are experiencing feelings of inadequacy and fears that you are not measuring up. The dream may be telling you that you are spending too much time hiding in the shadows of someone else. Alternatively, a mouse symbolizes minor irritations and annoyances. Perhaps you are letting petty problems or insignificant issues eat away at you. The dream may also be a pun on a computer mouse and your connection to work or to the virtual world.
