Seeing a giant in your dream means you are developing a sense of inferiority. Your giant is able to overcome obstacles, while you are not. If you continue to rely on the giant to do your bidding, then expect to be stuck in your present situation for a very long time.
If you dream that you are being chased by a giant, it might symbolize a sense of danger or threat. You might be feeling anxious or fearful about something in your life, or feeling as if you are being pursued or attack by something larger or more powerful than you. Also, the giant could symbolize a sense of vulnerability or weakness. You might be feeling a lack of control or power in your life, or feeling uncertain about your own abilities or strength.
In the waking hours, focus on your task and start nibbling away at it. How do you eat an elephant? One bite at a time.
