Have you ever driven somewhere and arrived wondered how you got there? Lain in bed at night wondering whether you locked the back door? These examples describe a state called waking sleep. Your body continues to function while your mind is somewhere else. This is described in Chapter 1 AWARENESS in my book Living in the Now.
But here is a truly extreme example of waking sleep! A New Zealand woman drove for hundreds of kilometres while asleep, sending text messages from her cellphone along the way. Police were alerted by a friend who said the woman had gone out in the car after taking sleeping tablets. They traced her car after learning that she had gone sleep-driving a few months previously and was fond of the beach. After 5 hours on the road, she was found slumped over the wheel in the driveway of a house she used to live in, with no recollection of her journey!!
