21.关于梦境的十个奇怪定律

Number 10

Not all dreams are in color. In fact, as much as 12% of people dreaming only black and white.

Maybe they grow up with only black and white television sets I don't know.

Number 9

Every face you see in a dream is the face you've seen before at some point in your life.

Our brains lack the ability to create completely new faces and objects.

So instead, your mind borrows them from your own memories to fill your dreams.

Number 8

One way to tell if you are dreaming or not to look at a book or a clock.

The pages of a book will be incomprehensible while dreaming and clocks don't operate normally inside dreams.
