I totally understand where she was coming from in regards to the paranoia lol

When you're experiencing psychosis, and it's raging pretty hard, pretty much everything anyone says can take on literally any meaning - including their tone of voice. Same with anything you read, and anything that happens.

To this day I hate coincidences, because during my psychosis I saw/heard quite a lot of them that absolutely were not real. Yet all that extremely-not-real stuff seemed 100% real, like the screen you're reading this on. That's one of the most insidious parts of psychosis. All that hallucinatory and delusional crap seems totally real when it's happening. Anyone who recovers from psychosis likely has this thought in the back of their mind, even if it's become insignificant and tiny over the years: "is this all actually real, or am I insane?"

You could say "would you like some water?" and they could hear it as normal, but interpret it as "hi, I'm god, nice to meet you" for example.

Or for me, something along the lines of "hey, we're gonna take some blood for blood tests" (with more words and in a very friendly/gentle tone) got interpreted as "soon you will be inducted into the group of those who know, but first we have to kill you" - which makes absolutely zero sense, which is why I hate typing it, but that was my experience. Keep in mind I'm strapped down at four points at this point, so that was a pretty scary time.

Imagine being strapped down, completely vulnerable, incapable of self defense, and everyone around you is 100% there to kill you. That's an example of what it might feel like to be psychotic, and terrified.
