Disappearing Things.

I don't UNDERSTAANNNDDD !!!!! Please I really need your help.
Things are disappearing and Im very worry about it.
And are things of my work it's the first time that happen to me and I don't know how to solve it my spiritual teacher told me once that things could disappear but belive me when she told me that I laughed and I did not belive it, but now that is happen me what should I do. Im freak and my hair end up and I don't understand it was a request for a new seller she had to fill in the form and I had to take home I put in a place that I wouldn't forget it I had the three documents together all of them are very important the new seller saw me I took all of them, I entered to my car and put the documents by my side I looked them again and when I got to my office there were only two documents and not the most important. I was very worry but I did not think what it could be. I called my home and I asked if I left the document there and they looked every where including my room and nothing.
Please, Im very very very worry.
My teacher told me that when a thing disappear it appear but in my case disappear !!!.
Fortunately, I have another chance to make the new seller sing another document and send to the main office 'till today. Im thinking that it could be a ghost by my side but I prefer not to think about it Im very chicken for those things. I watch ghost whisperer on tv and try to imagine myself as the main role but to tell the truth I would not like me.
Thanks a lot.
Cheers.
