When someone dreams of a crib, it typically means that they are comfortable with the person they are in their waking life. It also signifies that they are ready to settle down perhaps to have a baby and grow up.
Dreaming about a crib could potentially represent longing for something they missed out on at an early age or could suggest what they are looking for in their future life.
In dreams, cribs are interpreted as a symbol for a significant event, a person or an object. Thus, the dream can indicate that something is an important task to be accomplished.
