No one has been able to explain_____________________________or disprove it.

That is a good one. 

It's interesting, for instance it is well known that Abraham Lincoln had a precognitive vision of his own funeral 10 days before he was assassinated. He apparently was quite a bit into spirituality stuff too.

Precognitive visions are not that uncommon, people are often just reluctant to tell about their experiences of this nature.

3 good ones as well.
