Witchcraft dream?

Don't take all the dream in as it is, you need to take certain aspects such as:

Witchcraft

Witchcraft signifies some inner transformation or changes. It may also suggest that something or someone is manipulating you and your surroundings.

Sister

To see your sister in your dream symbolizes some aspect of your relationship with her, whether it one of sibling rivalry, nurturance, protectiveness, etc. Your sister may draw attention to your family role. Or the dream may also serve to remind you that someone in your waking life has characteristics similar to your sister. Alternatively, your sister may be a metaphor for a nun. In this case, she may represent some spiritual issues.

Pulling

To dream that you are pulling something refers to your burdens and struggles. You have difficulties accomplishing your tasks and goals. You need to unload and/or let go some of your responsibilities. Perhaps it is a relationship that you need to let go of. Consider also what or who you are pulling. Alternatively, the dream may be a pun on your "pull" or influence for some favor or decision.

Devil

To see the devil in your dream signifies fear, limitations, and negative aspects of yourself. You may be harboring feelings of guilt. It is time to release these feelings. Alternatively, the devil represents intelligence, cunningness, deception, and cleverness.

To dream that you fight off the devil indicates that you will succeed in defeating your enemies.

To dream that the devil talks to you suggests that you will find certain temptations hard to resist even though you know it is not in your best interest.

To dream that you and the devil are friends suggests that you are easily influenced and can be persuaded into doing something you do not necessarily want to do. Alternatively, you may be dealing with issues of morality.

Possessed

To dream that you or someone else is possessed represents a state of helplessness. You feel you are not in control of things.
