Yeah, I've noticed that after speaking with some of them. Though I've hit a few that don't even seem to realise they're dead. Yeah? I've kind of had a feeling I could be doing more but I haven't really tried much or done any kind of training.
There was a girl who I found. She was just lonely. She'd had a bad life and been murdered. That was... I don't know, kind of sad. But I've been warned off a few places by other ghosts. They say there's 'dark things' in them.
