Your protected space is how you can turn the outside world off. It may be very subtle, such as sticking your fingers in your ears while your head is under the hot shower. Thios little trick makes it sound like it is raining outside. This a favorite of mine. In doing it, my mind senses the rain, while making me feel comfortable as if I am shut in and no one else is around–at least until the “rain” stops. It is a simple little luxury of mine that allows me to think creatively, albeit for a short period of time.
