Spike in nightmares could be lupus warning sign: study

A rise in the frequency of hallucinations and nightmares could be an early warning sign of autoimmune diseases like lupus, according to a UK study.
Researchers called for doctors to ask about nightmares in the hope it could help detect when symptoms are likely to flare up in patients earlier.
The study by the University of Cambridge and King’s College London included a survey of 676 people with lupus, a disease which causes the immune system to attack tissues and organs, and 400 clinicians.
It also included detailed interviews with 69 people living with various chronic inflammatory autoimmune disorders, including lupus, and 50 clinicians.
