solipsism ocd... anyone ever have a weird obsession

Solpsism
Hey Everyone,
I have deal with solipsism thoughts before and have overcome them but now they have come back different and stronger. I started to think what if everyone wasn't real and they were just ghosts of people from previous lives. I know this thought is irrational but my OCD/ DP makes me feel as if its real or something that I should be certain about but im sure we all know certainty with OCD and DP is non existent. Could anyone weigh in on similar thoughts and what you did to recover?

I had very similar OCD obsessions when I was young. Unfortunately, I can't offer you much more than solidarity, because I just aged out of it and into other obsessions.
