By using this or other methods, you can keep yourself on the verge of sleep, but not actually 'drop off' and this is the 'sweet spot' this is where you want to be. In this state your mind is awake but your body is resting, and this is very conducive to visualizing, daydreaming, or in my case, exploring things I want to do or be in the future.
This afternoon, I had a strong sense of the house I want to live in, and I took a tour of that house today. I imagined sweeping the car up the drive, parking and going in the front door, making a cup of tea in the kitchen, and then exploring the other rooms. I imagined every little thing, the smells, the ambience, the creak of the doors, even the heat of cold of the walls and floors. I soaked up every minute detail, and accepted them as something that would come into my life. I have to say it was quite a tour! I think you would be impressed!
After my tour, I got back in my car, and left the house, knowing I would return, and gradually brought myself back to being fully conscious. What I hadn't realised, is that over 90 minutes had passed, and I hadn't even been asleep! by taking this break, I am energised now for the evening ahead, and with that lovely focus and mindfulness that follows relaxation or meditation, so I am able to fully devote my attention to my family tonight. But the thing you must know, is that these results will also come after 5 minutes, and you don't have to spend an hour or more, just spend a few minutes of time breathing deeply, relaxing, letting your mind either drift away, or focus on something you want to do, and then come back gently and continue your day refreshed, focussed, and relaxed! it really is amazing.
What possibilities do YOU want to explore tomorrow?
