Yep. During a pretty bad episode of delusional schizophrenia (for lack of any better diagnosis) I had that, many years ago.

I felt like I was either on the verge of a huge epiphany or I'd just had one, for a few weeks. Every time it was nonsense or couldn't be explained.

Luckily I have not relapsed and I have been off the antipsychotics for a few years

The only permanent damage is that every medical professional says I should never do psychoactive drugs. Which sucks cause they sound fun and I wonder if they'd help me get over some other problems I have. Maybe after I've retired.
