Miraculous vanishing laptop memory/ram cards while in use in my lap.

This is weird.  I was using my laptop when suddenly I lost power and couldn't reboot or get power.  Upon extensive checking, I have found that my ram/memory cards have disappeared from my laptop right in my lap.  No, they aren't here at all unless they are invisable.  I am alone in a remote area with only my cat and dog and am at complete loss for explanation of this.  Has ANYONE had this happen????
