Ariadne's Book of Dream
A sweater offers comfort and warmth around the upper body, including the heart, and thus may mention the need to improve your mood.
A pink sweater may express love, and a blue sweater may communicate peace.... Ariadne's Book of Dream
My Dream Interpretation
If the sweater was too hot or itchy, you are impatient to get started on something you have been thinking about for a long time.
If the sweater was too tight, you need to protect your reputation by cooling down your behavior with the opposite sex.
If you lost your sweater in the dream, you need to reconnect with a forgotten or neglected aspect of your own self.... My Dream Interpretation
