If Daqiang uses his abilities to enter someone's sleeping curse dream he will be immediately afflicted with the curse. That being said, it is possible for him to explore the dream this way. He will watch the person's dream as if it is his own but also be able to see the dreamers drowning. Near the end of the dream Daqiang will witness a strange black orb emitting dark energy... But other than that he won't be able to glean anything else. Yet.
