String Theory to Explain Paranormal??

According to String Theory, there are 12 (or more) dimensions. If you read Stephen Hawking or Michio Kaku, they will describe something called "Flatland". This is where a 3D being such as ourselves pulls a 2D being off of a paper and places him/her back down on the paper. To us, it is an everyday thing. However, the 2D being sees it as magic, or some other unexplainable phenomena. So, my theory from this is that ghosts, spirits, and the like could possibly exist in another dimension and know how to interact with our realm somehow. This may be the reason that we only see glimpses of their existence and why we can only catch the evidence via electronic devices. Of course, this may be able to explain interactive hauntings and not residual hauntings. Then again, residual hauntings may not involve interaction between dimensions or planes, as they are an interaction between times...if that makes sense.
