It's interesting how you described that process -- I actually distinctly realized around middle school that lingering thoughts led to visualizations and eventually sleep. I got good enough at training myself to close my eyes and start thinking about non-stressors/random thoughts to trigger fast and easy sleep, most of the time. It doesn't really work if there is something significant on my mind, like a work or personal issue.
