In your dream, seeing a deceased person is indeed a profound experience and carries significant meaning in Islamic tradition. The combination of feelings—frightening and peaceful—adds depth to its interpretation.

Key Symbols:

1. Deceased Person (الميت al-mayyit): Generally, seeing a dead person alive in a dream can signify a connection or message from the unseen world. It often represents unresolved feelings, memories, or lessons associated with the deceased.

2. Frightening and Peaceful Feelings: The mixed emotions suggest an internal conflict or duality in your life. Fear might represent anxiety or worries that are unresolved, while peace could symbolize acceptance or reassurance in some aspects of your faith.

Traditional Islamic Meanings:

• Seeing the deceased in a peaceful state can imply they are in a good station in the afterlife, as per Islamic teachings.
• Feeling frightened might relate to worries regarding your spiritual state or actions that need rectification or forgiveness.

Personal Interpretation:

This dream may be inviting you to reflect on your relationship with the person who appeared to you. If there are unresolved issues, consider if there are actions you can take, such as charity on their behalf or other acts of kindness. The peaceful feeling in the dream is a good sign and may indicate that the person has found peace.

Spiritual Reflection:

The Quran and Hadith emphasize the importance of prayers and seeking forgiveness for the deceased, which can be a source of comfort and mayilyah (intercession) for both you and them. Consider this an opportunity for personal growth, strengthening your faith, and remembering the transient nature of life.

If there are specific attributes or messages from the dream that stand out to you, they could hold personal significance and might be worth reflecting upon in your prayers (dua) and actions.

May Allah grant you clarity and peace in interpreting this dream and guide you towards wisdom and understanding.
