I dreamed that the floor of the house was sunk into a puddle, and it was getting bigger and bigger.

Dreams are very personal. Everyone has his own unique experience and background, so everyone's dreams may have different meanings. But from the perspective of general psychology, dreams can be the manifestation of psychological pressure and emotions in the subconscious.

According to your description, dreaming of a puddle on the ground of the house may symbolize some difficulties or challenges you face in real life. This kind of difficulty may make you feel uneasy, anxious or scared, just like the puddle in your dream is getting bigger and bigger.

This dream may also reflect your sense of helplessness or powerlessness in dealing with this problem. The appearance of puddles may imply that this problem is beyond your control, and you feel that you can't stop it from happening and expanding.

However, dreams can also be the manifestation of subconscious problem-solving methods. The appearance of puddles may mean that you are thinking about how to solve this problem, and the bigger the puddle, the more likely it means that you are thinking deeply and looking for a better solution.

Generally speaking, this dream may be a true reflection of your present situation or a psychological reaction. I suggest you think deeply about the details in your dreams and real life in order to better understand your emotions and the challenges you need to deal with.
