Been there and absolutely can see this happening, it is sometimes a prodromal symptom called a 'sign of reference' [1].

I recall during my first psychosis episode thinking a TNT logistics van contained a bomb and was being used as a terrorist vehicle to blow up a building (or maybe at the time I think it could have been targeting myself directly).

Also, in that same episode, the train stations in Sydney were being plastered on every possible space and surface with high contrast white on blue posters that said "HEY TOSSER!" [2]; it was an anti littering ad campaign bringing some levity to the situation. My mind was overwhelmed by both its alerting nature and the fact that everywhere I would turn I'd see a poster, and in my infirmity it felt like someone was pointing a finger an inch from my forehead arresting me to say I should stop being a tosser in the derogatory (Australian slang) sense (though my mind was contending with the many multiple meanings).

this seems reasonable to me, i don't have schizophrenia but i'm pretty sure i'd start stabbing a fridge if I ever saw it give me an advertisement
