You See I want to know what this reason might be!
All of a sudden The date 17 November 2011 is circled
With a blue pencil. And It has N2 Next to the circle what does
It mean? What's special about that day! I've asked all my
Family members but everyone said Nope not a clue.
Could It have been a ghost? It wasn't there before and no one has
Been in my room Except for the maid but she hasn't/doesn't Touch my calendar!
So What's happening I feel crazy..
And dizzy!
What does this all mean I also Had a dream about the number 17!
Maybe it has something to do with it.

I don't know if anybody could really answer that question here. I don't know if I'd be so quick to blame that on a ghost. While the paranormal can always be an explanation... it's just not likely. Do you sleep walk? What was the dream about that you had that involved the number 17?

Well there was a lady (a old one)
She kept repeating it 3 times 171717 And she also said something
About an elixir of life her name was Emily.

Well, it is possible for this to have spiritual origins. But that doesn't mean it isn't harmful. I wouldn't allow this to go any further. Don't make an effort to seek out this information as it can open a door to more stuff like this. Hopefully there won't be any more episodes... but if there are, make it known that you are not interested and tell it to leave. This very well could be a spirit, but not a good one.
