My neighbor hears voices

Hi,

since I've seen post about ocd here… can someone tell me if ocd can become schizophrenia?

I rent a flat, and my neighbor is on pills from ocd and anxiety issues. On most days, like 90% of the time, she’s OK, I didn’t even suspect anything until she told me about her meds.. I looked it up, and it doesn’t sound like anything scary. We have separate rooms, and we don’t even communicate much, cause she has night shifts and I work during the day. What bothers me is that she’s often on energy drinks, and we had a couple weird situations. One time she came into my room in the evening and said in serious tones that something in her head was urging her to throw my plant out. She then went up to the window and tried to do it, until I stopped her. She claims that she doesn’t remember it but I suspect otherwise. Last weekend I was with friends, and my neighbor told them she could hear what they were thinking about her. My friends just laughed, but I was freaked out cause I know about her diagnosis.

Should I be worried? She hasn’t actually done anything bad (yet?). And, like I said, most of the time we’re fine. But I’ve read other stories, and am thinking of what might happen when I sleep.
