You are dreaming of unknown sources of joy. While gifts are often associated with events that merit them, the giving and receiving of a gift speaks more about the relationship between the two parties than the reason for the giving.
If your dream includes another person involved in a gift exchange, examine that individual as a character aspect that is highly beneficial to you at this time. This is the case whether you are the giver or the receiver in your dream. Gift exchanges can be so charged with elation that many people are motivated to gift others in order to experience this elevated feeling.

Dreaming that you wrap an object reflects your desire to hide something; usually some aspect of your personality that is repressed. The opacity of the wrap indicates whether this rejection is deep. The act of unwrapping, however, indicates otherwise; It means that you begin to be more open.
