I Am Having Terrible Realistic Exhausting Emotional Dreams Ever Since

I am having terrible realistic exhausting emotional dreams ever since I started taking lyrica for a back injury I suffered at work. I have been treated for anxiety disorder and depression and on meds for this since I was 12. My behaviour, anger and frustration level has changed dramatically since taking lyrica. It I s affecting every aspect of my life. I am sure it is the lyrica. Could it be?
