It was horrible and i woke up stressed! What does dreaming of this mean? Really hope it means nothing too bad!

From "Dream Dictionary":
To see a dog in your dream symbolizes intuition, loyalty, generosity, protection, and fidelity. The dream suggests that your strong values and good intentions will enable you to go forward in the world and bring you success. The dream dog may also represent someone in your life who exhibits these qualities. Alternatively, to see a dog in your dream indicates a skill that you may have ignored or forgotten. If the dog is vicious and/or growling, then it indicates some inner conflict within yourself. It may also indicate betrayal and untrustworthiness.If the dog is dead or dying, then it means a loss of a good friend or a deterioration of your instincts. Also consider common notions associated with the word dog, such as loyalty ("man's best friend") and to be "treated like a dog".
To hear barking in your dream suggests that you are annoying those around you with grumpiness and fussiness. The dream may also be analogous to your tendency of barking orders at people, instead of asking or talking kindly. Alternatively, barking refers to unhappy and disgruntled companions. 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. Alternatively, it symbolizes disloyalty. To see a happily barking dog in your dream symbolizes pleasures and social activity. You are being accepted into some circle. If the dog is barking ferociously, then it represents your habit of making demands on people and controlling situations around you. Are you "barking" too many orders? Alternatively, it could also indicate unfriendly companions.
