Keep having different dreams that my boyfriend has an STD

We’ve been together for years. The relationship is definitely ending and it sucks, but that’s not the purpose of this post. Over the past year or so, i’ve had at least 7 different dreams of him getting an STD. Let me also say I do not trust him at all, hence why the relationship is ending, but this has gotten to be very strange. Just had a dream that his bestfriend told me he has HIV. Normally it’s me finding out in my dreams because I get it, or literally walk in on him cheating. I’ve never once dreamed about any of his friends, let alone having a 30 minute tell-all phone conversation. His bestfriend told me pretty much everything i’ve been feeling in the real world. This one felt so real because it reflected my real life. I had just left his house after an argument and began driving home when his bestfriend called me. We spoke on the phone for like 30 minutes until I got home and he told me about all the girls and everything i’ve been thinking. I used to only have dreams about him cheating and wrote them off, but then every cheating dream turned into an STD dream and at this point, it’s way too constant for me to ignore. This might sound dumb, but I think i’m going to go get tested this week. What could this mean???

UPDATE- The tests all came back negative. Happy about that, but still not sure why i’m having these dreams.
