You change/jump dimensions every time you make a choice. The jump you describe would be a very very big jump, and I've never heard or experienced
such a large jump before in my life.
Here are 2 posts that I think may help you a bit, I've written about this subject before.
Time does not actually exist. It could be passed off as a "dream", and maybe it is. I don't know. But if it did happen, then the above 2 posts
may help to explain it.
If you've ever experienced time "slow down or stop", IMO that is a larger than normal "dimension jump". Where you were actually on the path of
being dead, seriously injured or whatever. But then you were shifted into a dimension where things worked out better. The "shift" results in
extra "frames" being added as you traverse them, which gives the perception of slower time.
The rate in which the brain processes the "images" is called the flicker effect. It's used in subliminal advertising among other things.
Changing this flicker rate, results in much more being processed/seen. As well, if you sync'd things up perfectly within the flicker rate, the
person would never, ever, know the things between the "flicks".
Imagine you are on a boat in the ocean. You have a "flicker rate" of only 1 image per 5 seconds. That is a "frequency". Now, lets assume the
ocean is moving at the same frequency. 1 wave peaks every 5 seconds constantly. Guess what happens? The ocean will appear static and solid.
Because every "image" you saw of the ocean would appear to be exactly the same.
So, you could have say 5 people on that same boat, each with the same flicker rate, but each at different points in that frequency. Now, each of
them would be viewing the same ocean, but it would appear differnt to each of them. 1 would always see the top of the wave, one at the middle, one at
the bottom etc.
The only way you could see the "wave" of the ocean is when you are not in sync. Then you would see the motion of the wave and so forth. So,
when you are in sync with the ocean, you see "particles" or "solids", when you are not in sync then you see the waves.
So, in such a case, to get such a jump would be like 1 person at the bottom just offsetting a single second, and the reality they see before them
would be completely different.
The matrix movie btw contains a scene that is almost exactly what you are talking about. Neo meets he agents, they make his mouth disappear and
such, then he wakes up in his bed and thinks it was a dream.
Even if such was just a dream, I'm guessing you probably learned a lesson from it.
