A white dog visited me when I was sleeping

"To see a dog in your dream, indicate a skill that you have ignored or forgotten, but needs to be activated. Alternatively, dogs may symbolize intuition, loyalty, generosity, protection, and fidelity. Your own values and intentions will enable you to go forward in the world and succeed. If the dog is vicious and/or growling, then it signifies some inner conflict within yourself. It may indicate betrayal and untrustworthiness. If the dog is dead or dying, then it indicates a loss of a good friend. Alternatively, it represents a deterioration of your instincts.

To dream that a dog bites your on the leg, suggests that you have lost your ability to balance aspects of your life. You may be hesitant in approaching a new situation or have no desire to move forward with your goals."
