I woke up not being able to breathe and found out my cat passed away?

I just got back from a family reunion in another state. Before me, my brother, my mom and stepdad left, we had to figure out what to do with one of our cats. She's about 15 years old, and a week before we left, she developed a urinary tract infection (she's had one before), and she became weak. She wouldn't eat or drink unless we pushed it on her, and she had to take medication on her belly for a scab wound that kept reappearing after it dropped off. So with all these problems, we wanted to leave her at a pet hotel or at the animal hospital while we were gone. They wouldn't take her for some reasons, so we left her at home with my aunt. The first few days during our vacation, we got calls that our cat was fine. Then on the fourth night, I had some problems with my allergies and my whole nose was plugged up. This was the only time during our trip that I had real trouble breathing, and I had to breathe through my mouth. The next morning, my mom told me and my brother that our cat had passed away overnight. I know it's silly to think that my breathing problem had anything to do with my cat's passing, but I sometimes think about how people can tell if someone important in their life has passed away. Sooo is it possible that they could be linked? Or am I just linking two things together that don't relate in any way?
