Dreams involving prayer and respect for the deceased often signify a reflection on loss, grief, or unresolved feelings regarding someone who has passed away. The act of praying in your dream suggests a desire for connection, healing, or seeking guidance from a higher power during a challenging time.

The figure you could see only from the back, along with the warning against praying in a certain way, might symbolize an aspect of yourself or someone in your life that you feel is at risk or vulnerable. This could indicate concerns about how you or someone else is dealing with grief or the potential consequences of actions taken in emotional distress.

The scene set in your father's house and the people using the garden as a shortcut could represent a personal space or family ties that are being intruded upon or utilized by external influences. It may suggest that you feel your home or personal life is being affected by outside forces, perhaps related to your feelings about the deceased or how others are coping with the loss.

Overall, your dream may be prompting you to reflect on your feelings about loss, the way you or others cope with it, and the importance of honoring those memories while also taking care of your own emotional well-being. Consider how you can create boundaries in your personal space and address any unresolved feelings regarding the deceased.
