Well, this is going to affect my belief system...

Yeah.  With her being five years old, and having been asleep very shortly before seeing a traumatic event and it violating how we currently understand the Universe and its workings...I would tend to her perhaps having some kind of bad dream, maybe, getting up, opening the door, seeing the guy and confusing the memories when thinking back, the exact sequence of events.

It may be difficult to convince her of that though, especially if she is already inclined to believe in psychic phenomena, precognition etc  If so, you may want to pose the question of how many times she has failed to predict something happening, or has predicted something which has not come true.  Get her to consider the "hidden data".

agreed. that is the sensible conclusion, and the one which i had assumed for a number of years.  but, that was just the earliest story she has (given to show that if her tendency toward these things is due to a concussion, then it must have happened in early childhood). 
since i have been with her, there has been multiple instances where she has woken up and informed me that someone had just died.  and she was correct.  (she has had one false positive on this particular track record, but she wasn't as sure that time.)
Those examples i was present and sober for, and they totally violate the rules as i understand them.  so, when i consider the stories she has that i wasn't present for, i'm no longer dismissing the possibility.

i just don't know.
i got a witchy woman.
