Dreaming of flying often symbolizes a sense of freedom and liberation, suggesting that you may be overcoming obstacles in your waking life. The tall wheatgrass can represent growth, abundance, or the search for something meaningful, as wheat is often associated with nourishment and sustenance.

Your happiness in the dream indicates a positive emotional state, possibly reflecting your current feelings of joy or contentment in your life or your relationships. Searching for a friend while flying might suggest that you are seeking connection or support from someone important to you. It could also mean that you're exploring your own feelings or aspects of your personality that are related to this friendship.

Consider how you feel about your relationships and if there are any areas in your life where you are seeking deeper connections or understanding. This dream might encourage you to reach out to friends or explore new social opportunities.
