Seen a picture on the internet of a woman behind the wallpaper in a room. You can see her legs standing on the floor at the bottom. How would i create an image like this? Any help would be very much appreciated.

Do you mean you are not willing to actually arrange and fotograph the scene but want to combine and edit (existing) images in Photoshop?
If so a decent result will probably take some time to achieve.
Some of he overall light and shadow caused by the figure might be achieved with Bevel and Emboss, but the folds will probably need to either be painted or combined from other images.
A distorsion of the wallpaper pattern could be achieved with Liquify, Puppet Warp, the Displace Filter …
