Dreams?

I don’t think about my ex like that, or go to bed thinking bout him. Does anyone know what it means when I dream that we wanted to touch eachother but can’t bc we aren’t together anymore? In my dream he was crying, saying he was dying to touch me. I have this dream like every couple of months. And I wake up feeling some type of way. Does this mean he misses me? Or like what? Bc I know I’m not crying missing him to the point I dream about him .. ??
