I knew I felt something off this upload. Haunted, eh? Well, I'm hope you decided to go out for a walk after your tea and left this rose to the haunter. Also there seems to be a bit of a haze or perhaps it's some glare from the window on the back of the flower :)
Very classy and elegant image, love the subtle lighting. What looks like a kind of haze is the result of shooting against the light without adjusting the contrast level. I found that 90% of all digital cameras have got some problems with lighting situations like these which makes some PS editing necessary. I will try and play a bit around with your image and see what will come out.
