Dreams involving deities and spiritual symbols often carry significant meaning, particularly in relation to your personal beliefs and experiences. Here are some interpretations of your dream:

1. Seeking Guidance: Walking towards a temple can symbolize a quest for spiritual guidance or clarity in your life. It indicates that you may be looking for answers or support in your waking life.
2. Message of Transformation: The mention of Goddess Kali, who represents destruction and transformation in Hindu mythology, suggests that you may be facing or need to confront some difficult changes or aspects of yourself. Kali can signify the end of old patterns and the birth of new ones.
3. Encounter with the Mentally Ill: The mentally ill person claiming to have a message signifies the importance of listening to voices that are often marginalized or overlooked. It may encourage you to pay attention to your own inner thoughts or feelings that you might have dismissed.
4. Possession and Fear: The frail person possessed by an evil spirit could represent fears or negative influences in your life that you feel are overwhelming or threatening. This part of the dream may reflect anxieties or situations that you need to escape from or confront.
5. The Wall and the Pond: The wall blocking the entrance signifies obstacles or barriers you are facing, potentially in your pursuit of clarity or freedom. The pond at the back might symbolize a hidden emotional depth or a place of reflection where you can find peace or insights away from chaos.

Advice: Consider what current challenges or transformations you are experiencing in your life. This dream may be urging you to confront your fears and seek deeper understanding or healing. Take time for self-reflection and explore what changes you might need to embrace. Engaging in activities that promote mental and emotional well-being could also be beneficial.
