Dreaming of a house often symbolizes your sense of self, stability, and family life. The double-storey aspect may suggest that there are layers to your emotions or experiences—perhaps indicating a need to explore deeper feelings or aspects of your life.

The presence of lions and cheetahs can be quite significant. Lions typically represent strength, courage, and protection, but they can also symbolize threats or challenges that feel overwhelming. The fact that they are surrounding your house may indicate that you feel a sense of danger or pressure in your waking life, possibly related to your responsibilities as a husband and father.

Your sister-in-law, her wife, and their child staying over could symbolize family dynamics and the interactions between different family members. This might suggest that you are considering the impact of your extended family on your immediate family life or perhaps feeling protective over your loved ones.

Overall, this dream might reflect your feelings of vulnerability or protection in your family life. It could be helpful to consider what challenges you may be facing and how you can address them. Take some time to think about your current family dynamics and whether there are any underlying tensions or pressures that need to be acknowledged.
