Dreams dictionary: Sash
Dreams dictionary: Interpretation 1
To see or wear a sash in your dream indicates that you are putting up a front or facade. You are not letting others see your true colors. Consider the color and significance of the sash. Alternatively, a sash signifies restrictions. Your energy flow is being constricted.
Dreams dictionary: Miller Dream Interpretation
To dream of wearing a sash, foretells that you will seek to retain the affections of a flirtatious person. For a young woman to buy one, she will be faithful to her lover, and win esteem by her frank, womanly ways.
