Asalaam ula Kum,
I had a dream on various occasions that I am marrying or I am married to a princess. Furthermore, I more recently dreamt that my wife is related to the queen of my country, although in reality we don’t know her bloodline.
a`udhu billahi min ash-shaytan ir-rajeem
Bismillahi ‘r-Rahmani ‘r-Raheem:
wa `alaykum salam,
This dream can mean that your wife is a descendant from a noble line.
And Allah knows best.
