Answer 1:
A lot of scientists would like to know the
answer to your question. No one is really sure
exactly what a dream is. We know that your
brain gives you messages as if you were
experiencing certain sights, sounds, and other
sensations. All of these sensations are put
together from your thoughts and
memories. Scientists can define dreams by certain
patterns of brain waves, but we still
really don't know why people dream what they do.
The color/black-and-white issue seems to be
controversial. I have heard that some people only
dream in black and white and that it was more
common in males. I don't know if that's true. The
problem is that dream content can't be measured
directly. We can only measure what people
remember and report about their dreams. I
certainly remember dreaming in color, but maybe my
mind is playing tricks on me. Another person might
say he dreams in black and white, but some people
would say that he just doesn't remember the color
because it wasn't important to his dream.
I looked for some answers on the web and found
an interesting article at
dreams
A researcher thinks that the debate about color in
dreams started in the 1950's when TV's became
common in American homes. Back then, TV was in
black and white. He thinks that this caused
people to dream in black and white, or at least
think about the possibility. He thinks that the
question is rare now that almost all TV is in
color.
Do you think that a person who has
always been colorblind sees color in his or her
dreams? In my dreams, I can be cold, but snow
is never cold. Have you noticed differences
between your perceptions in your dreams and your
perceptions when you are awake?
If these sorts of questions interest you, you
might consider a career in psychology or
neurobiology. |
