In this world there could be a copy of yourself making different decisions and seeing places that somehow later manifest themselves in your dreams.
For thousands of years people have wondered about the meaning of dreams. Why do some people dream about future events? Why are some dreams full of hidden meaning?
Can some of our dreams be glimpses of events taking place in an alternate reality, a parallel Universe?
Our ancestors were as curious about dreams as modern scientists are today. Ancient Greeks and Romans believed dreams provided messages from the gods. In ancient China people treated dreams as a way to visit the world of dead. Ancient Egyptians were convinced that those who could interpret dream possessed special powers.
Many Native American tribes and Mexican civilizations believed dreams were a different world we visit when we sleep.
The word “dream” comes from an old word in English that means “joy” and “music.”
Today we know that dreams are often expressions of thoughts, feelings and events that pass through our mind while we are sleeping.
Dreams can be in color and include all the senses – smells, sounds, sights, tastes and things we touch. We know more about the science of dreaming because researchers can take pictures of people’s brains while they are sleeping.
Over the years scientists have learned a lot about dreams, but there are still many things that remain unknown.
