ELI5: How do dying people "wait to go" so they can see their loved ones one last time?

I've had over six family members/friends die over the past two years.

All of them had the same thing happen: they were losing to disease and wouldn't "go" until they got to see their loved ones for the last time. Every single one of them (who were expected to die anytime) waited days and even weeks so that their loved ones could arrive and say goodbye. Once they said goodbye, they all died minutes/hours after.

Many friends of mine also said the same exact thing happened to their family/friends too.

Basically, how does a dying person stay alive long enough to see their loved ones? What, scientifically, are they able to control or postpone in their body/mind that allows them to live long enough?

This is called confirmation bias. You don't remember the people who died without seeing certain members of their family. If a person is dying and being visited over a period of time by a number of their loved ones, the odds of them dying relatively close to one of those visits is pretty good. There have been multiple studies that investigate whether people can postpone death in order to make it to some social or religious event which showed that there is no data to support this, in contrast with some smaller, earlier studies that suggested that this might be the case.
