An article claims that many medical patients have an instinctual ability to predict sudden changes in their medical status  But the evidence given is anecdotal and should not be trusted  The case is analogous to empirically disproven reports that babies are born in disproportionately high numbers during full moons
Once that rumor became popular, maternity room staff were more likely to remember busy nights with full moons than busy nights without them
patients' predictions of sudden changes in their medical status are less likely to be remembered by medical staff if no such change actually occurs
