Seeing a house foundation in a dream symbolizes your strength, stability, or even the compromised structural integrity of a building or organization. Foundations are very important as they hold the entire weight of a structure, relationship, marriage, friendship, community, or even an organization.
This dream may reveal a need for you to work on your foundations. If you are in a compromise relationship, then this dream clearly calls for your effort in addressing that issue and working on building the relationship on solid ground, enriched with integrity, true love, and purity.

They are like a man building a house, who dug down deep and laid the foundation on rock. When a flood came, the torrent struck that house but could not shake it, because it was well built. 49 But the one who hears my words and does not put them into practice is like a man who built a house on the ground without a foundation. The moment the torrent struck that house, it collapsed and its destruction was complete. Luke 6:48-49
Your marriage foundation may be compromised due to unfaithfulness to your spouse. It is high time to reconsider your ways and turn to God, who can heal you of your backslidden state and also restore your marriage. (Jeremiah 3:22).
