Encounter with a Deity

Many years ago, there was a period of time that i was coughing profusely for months. Nothing seems to work to cure it.
One night i had a lucid dream.
In the dream, sitting in lotus position in front of me was Dzogchen Master Namkhai Norbu Rinpoche. (I attended half a seminar/initiation by him some years before while he was in Singapore). I bowed slightly in respect, he gestured me to move along to his left side. Here, I see this Deity, in front of me.

She addressed herself as Goddess 'S... a'. Should be Sitatapatra .. i think.. i wasn't catching it clearly. She gestured me to come forward. Our forehead touch.. there is an energetic exchange.
Then she says " Reaching completion soon'.

​End of Dream.

I wasn't really able to capture her energy here. She has an extra-terrestrial look.. her skin is pure white.. not Caucasian white but really white . Her eyes are larger than a normal human beings. Although very beautiful, she projects a fearsome energy.. or maybe i was just taken aback by her unusual appearance, I am not too sure.

2 weeks after the dream, I went to see a TCM physician. He prescribe some TCM for me, Not long after, my cough was cured.
