The meaning of richness is the opposite of what it seems. Everyone knows that dreams of material richness are pleasant and enjoyable. However, you must treat this type of oneiric image with caution. Temporal possession can bring you to think that it is definitive and that it will always last.
It is not like this, as reality shows. A dream of this kind can definitely remind you that you should not accommodate a situation of abundance, as it is possible that it will transform into one of shortage.
[1]Richness in a dream means poverty or contentment.
