During the COVID-19 pandemic, suicidal ideation was 2% lower overall than before, while nightmare frequency increased by 4.50%. Data from 9328 individuals across 16 countries showed that suicidal ideation decreased significantly in Austria, Sweden, and Bulgaria but rose non-significantly in Italy and Portugal. Participants with long-COVID reported higher rates of suicidal ideation (21.10%) than those with short-COVID (12.40%), though ideation did not differ by COVID-19 history alone. Nightmare frequency was higher in those with prior COVID-19 (14.50% vs. 10.70%), during active infection (23.00% vs. 8.10%), and in long-COVID (18.00% vs. 8.50%). Frequent nightmares during the pandemic increased the odds of suicidal ideation (OR = 1.
