"I don't think the flashbacks will go away anytime soon though. It's going to take a while for those to stop, as with any traumatic experience like that."
Kim was alone and asleep in her exclusive rented Paris apartment, when a gang of armed robbers somehow got inside on Sunday night.
Police in Paris say they are investigating the heist in which Kim was tied up and locked in a bathroom, before the men, described as white, French and middle aged, stole $10 million worth of jewelry.
No arrests have been made.
Adding to Kim's trauma, is the realisation that the incident, while upsetting, could have been much worse.
Said the source: "The scariest part for her throughout this experience is the fact that it could have been a lot worse, and she couldn't imagine what that would have been like for her children."
