If you are traveling and you arrived at once (or comparatively fast) from one place to another, most probably you're dreaming. (For example, you're in a car and in a second you're already in another village, town, city, country, mountain... planet.)
I will share something with you from my life. Bare with my wanders, in the end it very much ties into the quote above.
When I was a teenager, I always had problems going to sleep. I knew what the problem was, just not how to address it. The problem was an active mind. In order to sleep, one must be mentally calm to achieve sleep.
I stumbled upon a way to quiet the mind but was not wise enough to see where that might lead as unforeseen side effect. The way to quiet the mind that I adopted was basically a form of self hypnosis. A way to get the whole body to relax as well.
It started simple enough, get into a comfortable body position in bed, and start a mental process of telling the body muscles to relax, one by one, over and over. When that one muscle responded, move to the next and work through the whole body, including the brain. Over the months, this became a nightly habit. The self hypnosis part came in that while mentally and silently doing this, one closed their eyes and looked as far upward as possible through the closed eyelids. This has the effect of straining the eye muscles, which in turn induces the self hypnosis.
Over the months of practice I got really good at it, the time it took to do this dropping rapidly until I achieved a state of the feeling of floating above the bed by 6 inches or so, perfectly relaxed. As I continued to practice this the times it took to achieve this state became shorter and shorter.
I was also going ot college at the time. Being poor, I worked and paid my way through school but it wasn't easy. I lived about an hour's drive from the college and could not afford to buy a car, nor to pay for dorm fees to stay on campus. So I bused 50 miles every day, there and in the evening back. This worked fine with two exceptions. I had night classes 2 times a week. So I borrowed the family car for those two nights.
I remember on the way home, leaving a small town. From that point till arriving at the home town city limits, I remember nothing else. Thing is in this route home are some serious turns. Any one of which could have put me in the trees or off a high embankment. It literally scared me to no end that I had entered this relaxed state through highway hypnosis, without knowing it happened or occurred till arrival.
Today I am very much scared to drive anywhere on the open highways because of being able to go into this relaxed state. One can not unlearn what one has learned. I no longer drive when alone anywhere long distance. It's too easy to slip into this state of relaxation and too dangerous to ignore.
