" The insomnia I am talking about results from a mild state of possession, harmless to those around you, who sometimes even fail to notice it. It usually comes when you are completely engrossed in your work and overtakes you so completely that every aspect of your daily life becomes mechanical and provides only a colorless backdrop to action occurring only in your mind. It matters not whether at this time you are asleep or awake. The secret life pulses within you, and when you wake in the middle of the night you realize there is no way to stem its flow. "
