Roses are known symbols of love, passion, femininity, and unity.
To dream of roses means that you have faith in a current relationship or that joy is awaiting in a new area of your life.
If you dream that you stop to smell the roses, your dream is telling you to do just that. You need to see the good in the small things of life in order to find happiness. Dreaming of smelling roses symbolizes you feel happy and at peace.
A withered rose in your dream symbolizes a death or an upcoming ending of something in your waking life. It also means that you feel a loved one is growing distant, withering away like the rose you saw in your dream.
