Agreement In The Space Between Heartbeats

The other evening a thought popped into my head, one I felt like I had heard from years prior, but it may have been from something like a dream- like it was in the realm of the parley and/or of mind control. Essentially it was known that those that love each other would intentionally measure their breath and heartbeat and speech and pauses in speech such that they all happened in syncopated fashion, like a subconscious concert. This was because if one were to make an error in interaction, an error that might cause a coercion and harm love, the next beat of the heart, or breath, etc, could override or interrupt the process of the thought pattern forming. It was a lovely reminder, although now seeming like its place was likely not held in any mainstream publication here. Perhaps I applied my own reasoning to an effect that has been noticed in psychology in the interactions between lovers and others of those that love each other before, but where the reasons why these patterns can be seen have been unknown? There are so many subtle things we do unwittingly in body language, I would not be surprised if there were a deeper meaning for many of them, in the realm of tangible psychological or spiritual defense, even if such things might actually be called vestigial at this point.
