First of all, dreams have nothing to do with bad luck. They are often caused by people's memories during the day or the reappearance of childhood memories, that is, day-to-day thinking and dreams at night. Like your dream, it may be related to your childhood memories. What you should pay attention to is not the meaning of the dream itself, but the dream. It may have satisfied your childhood desire for the roof, but it didn't come true, so leave this desire in your dream.
Dreams are unconscious and disorderly links of information in the brain. Some are forgotten by you, and the information on the edge of memory will be called. So many dreams run counter to reality. Doesn't mean anything at all We artificially add personal subjective understanding to form unscientific dream interpretation. But real science shows that dreams have no specific meaning, just an extension of memory or the satisfaction of desire.
