This dream may symbolize a power struggle or conflict in your waking life. The female in the car with you could represent a person or situation that you feel is trying to control or dominate you. Sitting on her lap in the driver’s seat could suggest that you feel like you are being forced to take a backseat or give up control in this situation. The biting could represent emotional or psychological attacks, and your fighting back and hitting her head against the window could symbolize your attempts to defend yourself and assert your own power. However, the fact that she continues to bite you harder each time could suggest that this person or situation is becoming increasingly aggressive and difficult to handle. The mention of almost breaking the glass could symbolize the potential for this conflict to escalate and cause damage. This dream may be a reflection of your feelings of frustration and helplessness in dealing with this power struggle in your waking life.
