Sheet Music
To see sheet music in your dream represents sensuality and harmony, especially in some waking relationship. Perhaps you are lacking these qualities in your relationship.
Self Harm
To dream that you are harming yourself suggests that you are seeking attention. You are expressing a desperate cry for help. Alternatively, you are trying to disconnect yourself from the unbearable pain you are experiencing in an aspect of your life. If you also self-harm in real life, then you are urged to seek professional help.
Stencil
To see or use a stencil in your dream indicates a lack of freedom in some aspect of your waking life. You are bounded by barriers and obstacles. Someone is not letting you do what you want or be who you are. Alternatively, stenciling means that you are looking for some guidance and direction in some decision.
