Through much of my childhood I had insomnia. I would not sleep, or could not sleep. I mostly remember this for my time in Washington... third through fifth or sixth grade, I believe.
Most of my positive memories of my mother are of me laying in bed with her stroking my back, helping me relax so I could sleep. Sometimes that was the only way I could sleep. Sadly, that is one of the few pleasant memories I have of my mother. Not to say that I have many unpleasant memories, but that I just don't have very many at all.
If I couldn't sleep in bed I could often sleep in the living room or somewhere else. My father would play a record, which in those days was a large black disk made from vinyl with wavy grooves in it. A physical needle would ride in the grooves and the vibrations of this needle were amplified into actual music! Wow. (Hey you kids, get offa my lawn!).
Judy Collins, Moody Blues, Beatles, Joni Mitchell... so many of the artists of the time were my sleeping companions.
I'm listening to the Moody Blues right now, "A Question of Balance".
I don't fall asleep to music anymore, but if I can't sleep in bed I can still nap on the couch.
Hot weather, though, causes insomnia for me. I cure that by the simple expedient of air conditioning and a fan in the bedroom.
