Mind wandering is for me like the company of a dear comrade.
Comfortable and useful.
Unlocking the team of my subconsciousness.
As a teenager bicycling was my endurance training for my real sport volleybal, and the holidays with my parents were 4 week bicycling travels and camping through Belgium and Germany.
A lot of boring autopilot became daydreaming and mindwandering.
Not about fears, struggling issues and regrets, but positive digesting, forward and creative. Also a lot of going through playing patterns and scenarios of volleybal, digesting situations that happened, like looking at vids and doing it again.
After two severe bike accidents at 18 and 19, my right knee hit twice, I quit my heavy sport trainings, felt like a handicapped person, had suddenly heaps of free time, and after acquiring a good side income, private lessons, embraced the students life of going out every late evening, and spend my time after dinner typical with reading for two hours, followed by two hours mindwandering, beforing going out. I considered too much sleeping as a waste of time, and believed (without any evidence) that mindwandering as dream like state would be more effective, more focused. So I learned to switch to that trance like state and learned to "load" my mind with "direction" by conscious touching upon certain topics, conscious choosing personas for "internal discussing" before switching.
Later on in my life there was less and less time for it, too much interactions, until my job required a lot of travelling, most of which by car in the late afternoon early evening and after the phone calls died out and the rational digesting of the day was done, I switched again to regular mindwandering.
The method of "loading" my mind with "direction" for the mindwandering I used also for falling asleep. "Touching" on topics but not really going into them to prevent not falling asleep at all. The positive effect that I had the next morning under the shower a lot of answers to issues. I integrated that in my work by mostly having a drink in the evening with the people I more formally met the next day, hearing their issues, wishes in the evening, and coming back on it the next day.
I can recommend to anyone to find his own comrade of reflection, solution finding, creativity by mindwandering
