As I've said, our ghosts say that they aren't ghosts, but when we started discovering that they might be around, we didn't know that. In fact, we weren't even sure that they were here. All we knew was that strange things were beginning to happen. For my part, I didn't get scared, really. Okay, well... not much.
I tend to have a strange reaction to them, though. When one particular (this is where I get into their names - which I think they choose) ghost who calls herself Diana comes around, I cry. It's not bawling, but it's something like she wraps her arms around me and tears pour from my eyes. There is a sadness with her, but she's not bad. She is simply sad.
