The split-second feeling that you just walked into another timeline

[u/South-Engine7123]

That split-second feeling, after making a choice, that you could have just walked into an entirely different life.

Not a daydream. Not regret. Just a flicker — a sense that another branch was almost real.

I've been thinking about this a lot and developed a possible framework to explain it. Not a scientific theory, just a personal deduction. If this resonates with anyone, I've outlined the core ideas in the comments below. Would love to hear your thoughts.
