I came across this article about a man named Otto Loewi.
Otto was working to try to discover how impulses are transmitted by nerves.
He was working day and night, this article says, but with little progress.
Then he had a dream about the work. He scribbled some notes after the dream but then found he couldn't read them the next morning. (I can't tell you how many times I've done the same thing but I didn't do what Otto did next, which is a big lesson.)
Since Otto couldn't read his own notes on the first dream, he must have unconsciouly asked for more input because he had another dream the next night and was able to hold onto enough of that one to put it into action.
The result was a Nobel Prize for Medicine in 1936.
So keep dreaming, ask for dreams about your most important work and put dreams into action when it is obvious that you are being shown something about the work.
