Stars represent goals and ideals. In fairytales the heroine wishes on a star to request help in achieving her goals! When pursuing something new we are often encouraged to reach for the stars to put our very best into it. Like stars our goals and ideals are something we always look up to.
Colliding stars represent a clash of ideals – often leading to depression. This is usually with one or both parents. The parent in question is given by the gender of someone playing a negative role in the dream. It can also be with someone close to you whose opinion or authority matters to you.
Falling stars indicate depression – your goals and ideals are falling down around you.
