Dreaming that the house is going to fall down is a precursor to illness, or you are already sick.
Dreaming that the house fell down also symbolizes that an annoying thing has been solved. If your family is lucky enough to escape the disaster, it means that the trouble has little influence on the people around you.
There are two common situations when you dream that your house or someone else's house collapses. One means that there may be something wrong with your house, because the house symbolizes the owner himself. It must be something worthy of attention. Collapse also means that some of your troubles and messy things will leave you in some way and will not have much impact on yourself. In another case, if you dream that your house collapsed, it means that you have been under pressure to some extent recently. This kind of pressure may come from work or from trivial matters in life. Everything can be handled in a low-key way without too much trouble.
Dreaming that the house collapsed may be in a rainstorm or an earthquake, which means that your body is very unhealthy and you should pay attention to aftercare.
It is a good omen to dream that houses without relatives collapse. No relatives after the disaster indicate the health and longevity of relatives, so don't worry too much.
Dreaming that the house collapsed and many people died, but you didn't die, reflecting that you want more luck than others in real life.
