My stupid dreams

I do not know why I keep on having dreams where I talk to people and they don’t answer me, and not only that, but they act like they can’t/ don’t even see me and don’t even look my way..

First time I had this dream was with my mother, and I thought I probably dreamt that because she passed away, so my brain made it up as such because I know she can no longer respond to what I say..

But then I had the same dream with my sister, and last night the same dream with two of my colleagues..

I don’t think it is a coincidence, it must mean something..
