so my imagination has been becoming pretty vivid and it’s starting to scare me . is this normal in the recovery?
You could try deliberately using your imagination (in a non-triggering way). Maybe look around the room and imagine things interacting with the environment. I used to do that as a kid. Then many years later I went through a phase of doing it again thanks to NoFap lol. Maybe it's to do with the brain rewiring.
I think it probably is. I’ve been having very vivid dreams and nightmares that are like movies and go on for hours. I have lots of energy now. I’m more alert than I’ve been in a long time. My mind is always going every waking moment. And on top of that some nights I can’t sleep so my mind is always trying to figure out ways to do things, solve problems. My imagination has been going crazy. Definitely feels like my brain is rewiring. Our brains are finally beginning to heal. Going through lots of changes. Maybe you could take up a hobby where you can allow your imagination to go wild.
Try meditation... YouTube has many beginner videos to help you focus your mind. Good luck and stay vigilant
