Is there a name for the condition for a grieving person to see and have one sided conversations with a deceased loved one?

I'm not sure if there is a name, but it is very normal. I do it all the time. I don't see them but I do talk to them in my head and feel they must be listening. Don't worry about the way you a grieving, as long as you are allowing yourself to let all emotions out properly. I'm sorry for you loss, the pain will ease with time..

I am not sure whether there is a name/formal condition, but I do know that it is rather common. When I lost my best friend 5 years ago I would still call his phone and leave a voicemail, text to ask how he’s doing, and talk to him whilst I was making a cup of tea as if he were stood right there next to me. After moving away and since relocating back to our childhood stomping ground I’ve confronted the grief that I spent so long running from, but even now I admit I still often glance over at his photo and say good morning, and spend a good hour with him each Sunday at his resting place talking about everything and anything.
