Why does my brain do this? Strange, upsetting dream

The dream was a straight shot of my POV(point of view) .

I was seated at what I guess was a repast meal. Someone had passed away. I was looking at my mom. The feeling I had was "I'm so sad...my aunt MaryAnn is gone!".

I then woke up, temporarily relieved, but then reality set in, as I recalled that two of my aunts passed between 2021/22. And my aunt MaryAnn was one of them. 😭
