When I can tell something is up, I just call them "weird thoughts". Sometimes I get actual delusions where I can tell that no one would believe me or would think I'm crazy, but I still believe them. Sometimes I have zero insight. That's when I make bad decisions. For me, delusions are a lot more dangerous than hallucinations...

What I have to do is stop the weird thoughts before they become delusions. Otherwise it's like Inception where a thought becomes planted in your head and gets out of hand.

Oh, an even better comparison is like the baobab trees from the book The Little Prince. Catch them while they're fresh or they'll keep growing and become unstoppable.
