"Melody." Leona said, when we were in the Common Room the next week. "What was the dream you had? When you said you knew all this?"  
"OK." Melody took a deep breath and went into 'story-telling' mode. "I was walking along a corridor until I found the Defence Against the Dark Arts classroom. I was just going to keep walking until I heard footsteps behind me. I was really scared. But then you three came. And you walked right through me. It was like being a ghost. In the morning I thought, oh it's just a dream. It was more than that. Well, you walked inside and I heard loud voices. So, I screamed. My ghost thought you were being tortured. But my scream was silent. Anyway, McGonagall came past. I can't remember what she said. But then there was a light and then a flash. The flash kept going until I was in the same place. This time there was something glowing on the door. I read it and it was exactly what you described. But this time all four of us were there. I told you I couldn't tell the future. Then someone shouted the torture curse. The lights went out. We cast Lumos. Then they Apparated again. Then I woke up. And please don't think I apparently felt I'll to get out of the first bit. I was feeling sick... with nerves."  
"We don't think that." I said. Practically the whole Common Room were crowded around Melody. "But Mel... you can really tell the future."  
"Thanks." Melody smiled. "I just get scared. Every dream I have feels real."   
"I'm sure nothing else will go wrong." Dylan said. "It won't."
