Might potentially add a profile. I've died a few times, spent time as a ghost, there was a never ending list of problems. Including witnessing things I couldn't stop, trying to comfort loved ones, things you weren't able to finish when alive, etc.
I can interact with the dead, seeing and hearing them depends on the situation.
It seems like a good idea. I spent a lot of time talking to the dead even after I came back, and there's always something.
