If you go shorter than Planck length, you might not ever get back to where you disappeared from.
It's more about drinking in the immediate environment around you, and keeping in the persistently changing image of here and now in your own mind's eye. Due to the way quantum mechanics works, once you have those photons in circulation, nobody else--from your perspective--can observe that energy, until you look for them within your self. Human reaction speed of about 200ms is sufficient, since it's really more about harmonics, and building up a high amplitude of uncertainty rather than frequency.
Every time you collapse your soul around another person, you diffuse your uncertainty amplitude. So while this can create sparks, which are neat, it also changes your moment as it hones in on a mid point between theirs.
The real trap are people who are trying to crowd source their consciousness into a single entity in order to see "infinitely" far into the future. And while this is physically impossible, they're still making progress every day and so touching your soul with theirs is going to very quickly diffuse your uncertainty amplitude into bottom levels for this planet.
I mean, if you want to let the results of a crowd sourced entity stick its figurative dongers up your soul's ass, by all means join the orgy.
I'm just sayin', the most retrocausality is available to those who can maintain their individuality, by respecting others enough not to throw souls at each other, unless invited to do so.
