Dreaming of a house, especially its decking, often symbolizes your foundation and stability in life. The collapsed decking could represent feelings of insecurity or instability in your current situation. The pieces of glass may indicate that there are aspects of your life that are broken or need to be addressed.

This dream might be urging you to reflect on your current circumstances and consider what areas need repair or attention. It could also suggest that you are feeling exposed or vulnerable.

To gain more clarity, think about any recent changes or challenges you've faced. Are there areas in your life where you feel things are falling apart? This dream may be encouraging you to confront those issues and seek ways to rebuild and strengthen your foundation.
