You should be the youngest in the family. You have been taken care of by your family for a long time, which makes you more dependent on your family. But after all, I'm 22 years old and I'm going to be independent, and you should be traveling or want to travel recently. So on the one hand, you are full of longing for a long trip, but on the other hand, you are worried and scared about facing the world alone. So I hope to be accompanied by my family during the long journey, but I know that my family can't be with you all the time, so I lost my car in my dream and you were separated from everyone.
This dream is generally positive, and the road you are about to take is upward, full of surprises and hopes. Have confidence in yourself and start to believe in yourself. Moreover, even if your family is not around to accompany you, they will always support and encourage you.
