I suspect that we have all had dreams at one time or another during our lives that turned out to be helpful, informative, or even prophetic. There is ample evidence that our subconscious minds are alive and well in some kind of dark corner of our minds, and work for us when we sleep.
The article below describes how that happened in the case of several distinguished scientists, who maintained that something they saw in a dream inspired them toward the solution of a major problem that had eluded them during their waking hours.
It would seem that the phrase "I'll sleep on it" is more meaningful and productive than might at first seem to be the case.
And to extrapolate from this, wouldn't it be extraordinary if a scientist involved in the hopefully future discovery of the cure for cancer, frustrated at being unable to reach that discovery in the lab one night, later reports that he fell asleep, possibly even at his workstation, and then had a remarkable dream, full of amazing images, and with perhaps a storyline that, upon his awakening, led him to the answer he had been seeking, the cure for cancer?
What would such a dream be like, what kind of strange, wonderful, symbolic images would it present, to inspire its waking owner to this great discovery, the cure for cancer?
How fascinating it would be if the inspiration for finding the cure for a major disease such as cancer should come not from experiments or scientific investigation, but from a dream.
If such a dream ever does happen, it will take its place among those discussed below as one the great dreams of history. https://www.wonderslist.com/famous-inventions-inspired-by-dreams/#:~:text=here%20are%20top%2010%20famous%20inventions%20inspired%20by,world%e2%80%99s%20first%20automatic%20sewing%20machine%20from%20a%20dream.
