Douglas Heingartner shared the findings of a Danish research paper in Psych News Daily which suggested a majority of respondents have useful dreams:
The results showed that 62% of the participants said they’d had dreams that were of help, or of good use. About 56% said they’d had dreams that influenced their opinions about others, and 54% had had dreams that changed their behavior. [..]
Among the 62% of respondents who reported having had helpful dreams, the most frequently-cited area of help was in assisting with creative tasks. This was followed close behind by emotional problem-solving, with “providing personal insight” coming in third. [..]
The findings of this study represent “huge potential for a major part of the general population,” the authors write, “in terms of using their nightly dreams for solving waking life problems to a much greater extent.”
I’d score myself among those respondents too, but not even for creative reasons. I used to solve so many programming problems in my sleep when I was a full-time developer; not necessarily in a dream state, but I’d wake up with that euphoric Eureka! feeling all the time. I also frequent an island cafe with my late mum when I need life advice and guidance.
I’d love to learn more about the subconscious; I’ll bet there’s a whole world there waiting to be explored and understood further.
