I take statins and my best self-analysis is that it gives me nightmares. I can't count the number of times I have woken up with bad dreams. However, I think it is my brain trying to regulate heart by causing it to beat harder. When I exercise, I usually do not have these nightmares, or maybe I am too tired to notice them.
I got prescribed Rosuvastatin and got extremely vivid nightmares to the point of waking up unrested. I thought I was the only one because I could find much online. The dreams and nightmares are so intense I have stopped the statin.
Thank you for recommending me exercixe. That might be the answer.
