Dreaming that the house collapse is a sign of illness, or that you are already sick.
There are two common situations when you dream of the collapse of your own house or someone else's house. One means that there may be a problem in your house, because the house symbolizes the owner himself. If such a situation occurs in the house, it must be something worthy of attention. Collapse also means that some of your troubles and messy things will be far away from you and will not have much impact on yourself. Another situation is that if you dream of a house collapse in your dream, it means that you have been under pressure in some aspect recently. This pressure may come from work or from trivial matters in life. Just handle everything low-key and don't need to bother too much.
Dreaming that a house collapsed also symbolizes that an annoying matter has been solved. If your family is lucky enough to escape the disaster, it means that the trouble has little impact on the people around you.
