As an adult, I had a television in my bedroom for about five years. Not only that, but the alarm clock is right next to my head, my phone sits on the nightstand, and my laptop was on the floor beside the bed. My doctor said I should remove all of these things from my room to eliminate all the electrical energy from my room. I removed the TV and laptop, and whaddayaknow, I sleep better, with less crazy dreams.
Most of my ideas come from my dreams. Of course, at times they've come from other 'what-if' circumstances, or hit me while on the back of my husband's Road King, but I tend to remember the dreams and nightmares more often. Which, by the way, would contradict the whole 'remove the clock and phone from beside your bed' idea.
Do you rely on outside stimuli to awaken your creative senses? Or do you prefer a solitary walk to get the juices flowing? Do you need silence, or do you prefer some inspirational music to get you in the mood?
