Your dream appears to be rich with symbolism and may reflect several underlying themes in your life. Here are some interpretations of the key elements:

1. The Glass Shard: This magical item symbolizes clarity and the ability to see deeper truths or realities. It may represent your desire to gain knowledge or insight into something profound.
2. Writing 'Zeus': Zeus, as a powerful figure in mythology, represents authority, control, and the divine. Writing his name could signify your yearning for understanding the divine or your own quest for power and knowledge. However, it might also suggest a confrontation with forces beyond your comprehension or control.
3. Your Sister's Reaction: Her fearful expression might indicate a warning against pursuing knowledge or power that is not meant for you. It suggests that some truths may be too overwhelming or dangerous to confront.
4. The Feeling of Dying: This aspect of your dream could symbolize a transformation or a rebirth. The sensation of being pulled out of your body may reflect a feeling of disconnection from reality or an exploration of your spiritual beliefs and fears.
5. Endless Stream of Words: This could represent the vastness of knowledge and information available to you. It may also signify confusion or a struggle to find meaning in everything you encounter, particularly in the context of your interest in fiction and magic.

Overall, your dream might be urging you to reflect on your pursuit of knowledge and the potential consequences that come with it. It can be a reminder to approach your interests with caution and awareness of your limits. Embrace your passion for fiction and magic, but consider the balance between curiosity and the risks of venturing too deep into the unknown.

If this dream continues to resonate with you, it might be helpful to explore these feelings further through journaling or creative expression.
