As regards my present manner of life, I must give a foremost place to the insomnia from which I have suffered of late. If I were asked what constituted the chief and fundamental feature of my existence now, I should answer, Insomnia. As in the past, from habit I undress and go to bed exactly at midnight. I fall asleep quickly, but before two o'clock I wake up and feel as though I had not slept at all. Sometimes I get out of bed and light a lamp. For an hour or two I walk up and down the room looking at the familiar photographs and pictures. When I am weary of walking about, I sit down to my table. I sit motionless, thinking of nothing, conscious of no inclination; if a book is lying before me, I mechanically move it closer and read it without any interest -- in that way not long ago I mechanically read through in one night a whole novel, with the strange title "The Song the Lark was Singing"; or to occupy my attention I force myself to count to a thousand; or I imagine the face of one of my colleagues and begin trying to remember in what year and under what circumstances he entered the service. I like listening to sounds. Two rooms away from me my daughter Liza says something rapidly in her sleep, or my wife crosses the drawing-room with a candle and invariably drops the matchbox; or a warped cupboard creaks; or the burner of the lamp suddenly begins to hum -- and all these sounds, for some reason, excite me.
