Supernatural Occurances

Is there any scientific or mathematical evidence of clairvoyant or "supernatural" occurrences or phenomena? I know that asking this is trampling the definition of supernatural, but I'm curious if there are any cases like this. If you do answer, please cite a source.

I see where you're going with this, but you're not quite there. Take that thought process a couple steps further:
If it can be sensed or experienced from the natural world, it is not supernatural by definition. Thus, no one can possibly have ever experienced anything supernatural. Thus, there is no evidence for supernatural events or beings. None. Thus, all descriptions of supernatural events and beings are purely imaginary. Thus, the supernatural does not exist. Burden of proof, Occam's Razor, etc, etc, etc.
Maybe later I'll post a rant.
