Taking into account the high stature of the giraffe, when the animal appears in your dream you should interpret it as an advice that you should think about your actions more deeply and try to re-analyze your life aims and what you want to achieve. Therefore, try to make a general image of things and of what is happening in your life; analyze it before taking any important decision or making a major step towards the future. Exactly like the incredibly tall giraffe, which has a very broad view of things from the height it looks at them, you should try to have a broader view of things happening in your life and then analyze them as objectively as you can.
If a giraffe appears in your dream it may also be a forewarning that you should not interfere into other people's business and you should only take care of your own. Therefore, do not stretch your 'neck' too much and limit yourself to your problems and business only.
