5 Interesting facts about dreams:
- People who become blind after birth can see images in their dreams. People who are born blind do not see any images, but have dreams equally vivid involving their other senses of sound, smell, touch and emotion. It is hard for a seeing person to imagine, but the body’s need for sleep is so strong that it is able to handle virtually all physical situations to make it happen.
- Within 5 minutes of waking, half of your dream if forgotten. Within 10, 90% is gone. The famous poet, Samuel Taylor Coleridge, woke one morning having had a fantastic dream (likely opium induced) - he put pen to paper and began to describe his "vision in a dream" in what has become one of English’s most famous poems: Kubla Khan. Part way through (54 lines in fact) he was interrupted by a "Person from Porlock". Coleridge returned to his poem but could not remember the rest of his dream. The poem was never completed.
- Our dreams are frequently full of strangers who play out certain parts - did you know that your mind is not inventing those faces - they are real faces of real people that you have seen during your life but may not know or remember? The evil killer in your latest dream may be the guy who pumped petrol in to your Dad's car when you were just a little kid. We have all seen hundreds of thousands of faces through our lives, so we have an endless supply of characters for our brain to utilize during our dreams.
- If you dream about some particular subject it is not often that the dream is about that. Dreams speak in a deeply symbolic language. The unconscious mind tries to compare your dream to something else, which is similar. Its like writing a poem and saying that a group of ants were like machines that never stop. But you would never compare something to itself, for example: "That beautiful sunset was like a beautiful sunset". So whatever symbol your dream picks on it is most unlikely to be a symbol for itself.
- This is called Dream Incorporation and it is the experience that most of us have had where a sound from reality is heard in our dream and incorporated in some way. A similar (though less external) example would be when you are physically thirsty and your mind incorporates that feeling in to your dream. My own experience of this includes repeatedly drinking a large glass of water in the dream which satisfies me, only to find the thirst returning shortly after - this thirst...drink...thirst...loop often recurs until I wake up and have a real drink.
- Believe it or not, your body is virtually paralyzed during your sleep - most likely to prevent your body from acting out aspects of your dreams. According to the Wikipedia article on dreaming, "Glands begin to secrete a hormone that helps induce sleep and neurons send signals to the spinal cord which cause the body to relax and later become essentially paralyzed."
