In the realm of dream interpretation within Islamic tradition, the lizard, or "سحلية" (sahlia), can hold diverse meanings. The dual nature of your dream—being both frightening and peaceful—suggests an internal conflict that may reflect both a warning and a sense of calm from Allah.

Key Symbols and Meanings:

1. Lizard (سحلية / Sahlia):
   • Frightening Aspect: In some interpretations, a lizard may symbolize deceit or hidden threats. It could represent a challenge or situation in your life that requires careful attention.
   • Peaceful Aspect: Alternatively, it can also symbolize adaptability and survival, suggesting a time of overcoming difficulties with grace.

Personal Interpretation:

Reflecting on your life situation, this dream might be indicating an area where you feel both apprehended and at peace. It may imply the presence of a trial or challenge that you are equipped to manage. Consider what in your life feels uncertain yet manageable with patience and trust in Allah.

Spiritual Reflection:

Allah's messages can come in subtle forms, encouraging us to rely on our faith. The fear you felt may be a reminder to seek protection and wisdom through prayer and remembrance of Allah. At the same time, the peaceful elements can reassure you that Allah is guiding you towards growth and betterment.

Remember the words of the Prophet Muhammad ﷺ: "A good dream is a part of forty-six parts of prophethood" and if ever a dream troubles you, turning to prayer and seeking refuge in Allah is advised.

May this understanding bring clarity and peace to your heart.
