To see a scarf in your dream symbolises self-restrictions. You may be too controlling of your emotions instead of expressing them. Alternatively, you feel that your voice is being muffled.
To dream that you are wearing a scarf suggests that you are separating your mind from your body. You may be relying too much on how you think, rather than how you feel or vice versa. Alternatively, the dream means that you need to tell yourself that it is mind over matter.
