, May I clarify, are you asking if psoriatic arthritis causes nightmares?
It has not caused nightmares for me, however, some of the medication I have used in the past, for pain, etc, has affected me in this way. Personally, my psoriatic arthritis keeps me awake due to pain levels., that is for sure. I am sharing an article with you about this: https://psoriatic-arthritis.com/living/mattress-sleep.
