Being a colour dreamer, I never considered that there would be people out there who would dream in black and white, or both; until I did a little research and read a few articles.
I also read an interesting scientific theory that suggested that the majority of black & white dreamers were people over 55 who mainly had access to only black & white TV, even after colour was first introduced, which suggests that the colours on TV influenced the colours of dreams.
I hadn't heard that one before, and although the results of that study seem to demonstrate that, I think there's a different reason for black & white dreams, though I'd have to do some research to find my answer and then prove it with other results.
Later in the article, it brought up a debate about how reliable our memory is and whether those people were recalling dreams, or just recalling what they thought was a dream, but possibly a different creation in their mind that included a combination of dreams and reality; another interesting thing to think about.
So, how do you dream? And what do you think about the dream theory and debate topic?
