A Ghost...?

Surrounded by magic
With things we can't explain
You see it happened one time
That left an unusual pain

You see it was a weird Friday
No other that is the same
The items around my house had moved
It seemed just like a game

It started off with money
And then with some keys
But I thought it was my sister
But she was no where to be seen

So I thought it was a ghost
As I could not seem to find
The items of mine that I loved
So I chose to write this rhyme

I want to know if this is biased
Or if it is just me
To other people 'seem' to lose things
A ghost it must be
