Dreams are actually a reflection of people's daily behavior, which is often said.
Whether you can dream about agricultural trucks or use an attitude actually reveals that you have the experience of living in the countryside and only dream when you are almost hit by an agricultural truck on the road during the day.
As for what sand represents in your shallow consciousness, it's hard to say.
You seem to have something on your mind that you don't want anyone to know except your father.
Labor, parents, is it a career puzzle? Clear your head and talk to him.
Generally speaking, dreams are not a sign of anything in the future, but the release of pent-up thoughts in the past.
Of course, meaningless dreams are actually the majority, and only repeated dreams with strong feelings have the value of analysis.
