Is there a name for this weird occurrence?

Awhile ago me and my bf were going to go to a baseball game on a friday. I woke up early that day and had a missed call and vmail from him. I was going to run errands so I didn't call back or listen to the vmail. I just texted him while on errands and we didn't really text about anything just small talk. So while he was texting me, my sister was also texting me saying I went over my phone bill $50. I hadn't really gone over though she just read it wrong. So I texted him "OMG I almost had a heart attack" and he was like um why? So I said my sister mistakenly said I owed $50 extra on my phone bill. He was like oh you didn't listen to my vmail and I'm no why? He was like I left it to say my dad just had a heart attack. Then of course I was like wow I can't believe I just mentioned heart attack like 1 sec ago. And it's strange because I never ever even use that expression. So I was thinking this was sort of an omen but not really since I technically didn't predict the future. It's just weird I mentioned heart attack right then. Is that weird or just a coinkidink.
