Question:
i am a 18 year student i saw in a dream that i performed ghusal from a stream waterfall and wears white shalwar kameez and i see my hands very white and healthy.
Answer:
Hands represent your ability and power, so by keeping your heart pure, as represented by the ghusl, and keeping your connection with your spiritual master (because waterfalls come from up high and mountains represents great saints), you will be granted ability over many things, which you must use for good.
