Not sure if coincidence or really means something?

So this may sound crazy, but my bf and I both had a really horrible day on Monday, like I had a meltdown and he was super down in the dumps. We don't talk until later in the evening so we didn't know until later that the other one was feeling the same. We kinda got to wondering if it was just a coincidence or if we are somehow "linked". We are long distance, this isn't the first time there's been some times when we've both unknowingly had the same feelings. There has been a couple times one of us was sick and later found out the other was also feeling kind of ill.
Just wondering if there could be something to that?

This is a normal thing that happens when you are in a relationship with someone. The both of you becomes one, and what affect one affects the other.

This isn't a coincidence but a natural phenomenon. I'm married and when I'm sick my husband is sick as well. It shows there is a bond between you two.
