Weird vivid dreams

Not sure why and what is causing them as I am not on any prescriptions right now other than blood pressure meds. Been on those for many years now. So I dream last night that I murdered 2 people. In my dream I knew them but in real life no one I knew. And everyone around me was trying to cover it up in the dream. I was getting really frustrated cause I knew it was wrong and I wanted to go to police to report the crime. I knew I was gonna go to prison but I rather be in prison than have the guilt. Maybe it reflects what is going on IRL with some guilt I have over family members not able to pay their mortgage due to job loss. And all the good blessings that have been bestowed to me and DH. I don't know. Really tired of the vivid dreams though. Seems they are getting more and more frequent. Not sure if it has anything to do with Lyme or not. Or just some weird side effect of getting older, maybe hormones. Not sure. Will have to ask DR again when I see him in couple of months....
