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.
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.
