Nightmares in the general population: identifying potential causal factors.

https://www.ncbi.nlm.nih.gov/pubmed/28712041

RESULTS:

Nightmare occurrence, adjusting for negative affect, was associated with higher levels of worry, depersonalisation, hallucinatory experiences, paranoia, and sleep duration (odds ratios 1.25-1.45). Nightmare severity, controlling for negative affect, was associated with higher levels of worry, depersonalisation, hallucinatory experiences, and paranoia (R 2s: 0.33-0.39). Alcohol use and physical activity levels were not associated with nightmares.

and sleeping too long gives more REM time, increasing amount of time for nightmares.
