Hm. Depending on my mindframe at the time, I might answer: 1. Yes, many times during my childhood when I read Casper the Friendly Ghost comics. 2. No, I don't believe in ghosts. 3. I might mention the weird thing that happened the summer when my grandmother died. I kept her ashes in the broom closet on the front porch, and one Saturday morning I discovered the front door open... around the time when she would normally have left to go shopping. There was no reason for the door to be open, and I know I'd closed it the night before. The actual explanation? To this day, 23 years later, I have no idea. 4. Or, if getting really personal, I might mention the time when I absolutely felt the presence of one of my cats who had died some months before. It's like she was on the bed beside me, wanting a pet and cuddle. That was unsettling. As for body language during all this, who knows? I can't predict that. And as we were informed, the actual words don't matter as much as how the person acts and reacts. Are the body movements, the facial expressions, etc. congruent with the words being spoken? I watched an interesting video a few days ago about how to spot if someone is lying. Some of the signs displayed by the subject were obvious, even before the presenter explained what signs some interviewers tend to miss.
