Yea it is quite common! And it was quite strange as I'm not religious at all, yet have had somewhat religious delusions here and there.
I can't remember how did I finally get over it myself. Probably was humbled by life somehow!😅

I haven't had that kind of experience, but can imagine it! I had more delusions of otherworldly beings in our world or that other people aren't real. When I was younger I also thought that I'm the only conscious being, "Messiah".

I've got schizoaffective and ADHD too. It's a struggle, honestly. But I live a good life! I have my small business and I work full time from home too. My employer has been very supportive, I am lucky. I have understanding partner and friends. They keep me grounded. Best of luck!✨
