Yak — a reflection of all the good that represents the animal, power, ruggedness, endurance, generosity. The need for personal power. Reflection of a blind rage.
To see a yak in your dream, represents your uniqueness and dependability. The yak may also be pun on yakking too much. Maybe you should stop talking and listen more.
Self-protective, reliable, persistent, perserverant, perhaps disagreeable. Dreaming of this animal can represent:
Having too much of one of these qualities, or that you could benefit by being less this way
Not having enough of one of these qualities, or that you could benefit by being more like this
Someone or something in your real life with whom you associate one of these qualities (an event, situation, threat, etc.)
For more clues, pay attention to what the animal was doing or any particular characteristic that stood out.
