Where Do Dreams Come from

Do you often dream at night Most people do. When they wake in the morning they say to themselves, "What a strange dream I had! I wonder what made me dream that. "
Sometimes dreams are frightening. Terrible creatures threaten and pursue us. Sometimes, in dreams, wishes come true. We can fly through the air or float from mountain-tops. At other times we are troubled by dreams in which everything is confused. We are lost and can’t find our way home. The world seems to have been turned upside-down and nothing makes sense.
In dreams we act very strangely. We do things which we would never do when we’re awake. We think and say things we would never think and say. Why are dreams so strange Where do dreams come from
People have been trying to answer this since the beginning of time. But no one has produced a more satisfying answer than a man called Sigmund Freud. One’s dream-world seems strange

When the light enters our eyes, special cells tell our brains about the light. These cells are called photoreceptors. Light is made of little bits called photons. When the sun shines, trillions and trillions of these little bits of light fall on the earth. The photons bounce off of almost everything and some of them enter our eyes. Those bits that enter our eyes allow us to see. So, where does the color come from Starting in the 1600s with Sir Isaac Newton, scientists have believed that there are different kinds of photons. Different types give rise to our sense of colors. The different photons are said to have different wavelengths. Sunlight contains all the different wavelengths of photons.
