My sempai's nightmare

I still remember one of my sempai's scariest nightmares... She tells me that it was so vivid. Here's how it went:
There were four of us--Me, sempai, White and Blue. We were going to her family's vacation house (This house is real). When we got there, we were playing around. There was also this little girl who looked like sempai's cousin... Anyway, we were running around in the backyard... By the way, the backyard was cemented, but there was a tree growing in the center. Also, behind the vacation house were stairs going down somewhere. It was supposedly a storage room... Anyway, the five of us took a rest and stuff. If I remember correctly, sempai told me that she (in the dream) was shown a picture of the little girl plus another little girl who had died... Then when she looked up, the little girl was gone, and she heard this screaming... It was the little girl calling out someone's name. Then, the scene before occurred again... Me, White and Blue and the little girl were playing around again, but this time sempai was just standing there, watching us. Then again, there was screaming again... But this time sempai could see the little girl. Over at the stairs, the dead little girl (the other one; remember the picture?) was standing there, wearing a black hood. Her eyes were all black; all of it. Then suddenly, me, white and blue all grabbed sempai's neck and we tried to choke her to death. Our eyes were as black as that little girl's, then sempai woke up...

notes:

• According to my sempai, she had this dream for two consecutive nights... But it's all over now. This occurred some two=three months ago.... But it's still odd.
• Sheez, writing this gave me the creeps. I had to play "Don't you know who I think I am?" and "I found a way (Drake Bell)" Over and over til I was done...
• Well it's all over now, but don't you think there's a meaning to it...? After all, Job 33:15 says: "Sometimes in the night, He uses terrifying dreams to give us warnings." (CEV)
