Please forgive me if this is the wrong place to ask.

I get this recurring dream of my father, who's passed away in real life.

The thing is, in the dream, there's this understanding of he's always back from the dead but it's this wrong feeling, like he's half-dead, half alive, not like when a loved one who's passed visits in a dream.

It's hard to explain but it's not a good dream.

It's like in the dreamworld he's still in our life, but I know, in the dream, that he's not alive, and it's almost like this bad feeling like "but we buried him! Why is he back?" and this wrong feeling, and like he's woken up from his coma but it's too late, and even in the dream the last time I had it, I said "I wish he would just either be completely dead, or completely alive!" and I felt bad afterward saying it in the dream... but it's this terribly frustrating, unsettling dream where he shouldn't be there.

It's kind of ghostly, a dark dream, he's not really saying or doing anything, he's just "back." Does this make sense? Does anyone have any insight, is this a common dream with someone who's passed away?
