A dream about sweeping water out of your house indicates a need to get something out of your life that does not belong there. Water gets everything wet and seeps into cracks and crevices, so the dream is about something that is "flooding" every aspect of your life.
The dream means that you have unfinished business that needs your attention. In this dream, the house is your life. It is time to "clean house" in the sense of finishing neglected tasks and getting yourself "cleaned up."
If the question refers to sweeping the floor, as with a broom or vacuum cleaner, it suggests that the dreamer feels that something needs to be swept away or cleaned out of one's life.
it means you probably didnt go to the bathroom before going to bed, and you had to pee
In this dream, the water represents some overwhelming problems. The dream presents a literal depiction of expressions such as, "our mortgage is underwater," which means owing more than the house is currently worth. But the grandchild in this dream probably also is a symbol, representing the dreamer her/himself or something innocent and precious, like the grandchild.
it could mean that underneath your house is a barreal ground or it could mean nothing
The dream suggests that the process of eliminating a nasty problem resulted in the destruction of whatever provided the solution. Perhaps an expensive remedy provided only a single use.
The dream expresses feelings of physical exposure and the lack of basic needs.
Water bugs walk on water. So this dream might reflect longing to do the impossible or to rise above common problems.
This appears to be a reassuring and comforting dream. The new house symbolizes your father's new phase of existence beyond the bounds of death.
Your house is a metaphor representing your life. Having a classmate in your house in this dream merely illustrates this person "in" your life. It does not predict anything in the future. Any further meaning depends on how you felt about having this person in your house.
Cats typically hate water. So this dream probably represents the dreamer's feeling of being in an awful situation.
You may have underlying fears that the water isn't clean. On the other hand, you just simply had a weird dream.
