Not really ghostly, but along the same general lines.
I have two sisters, one is 17 and one is 13. We can all pick up on things that the others are thinking and feeling. I feel like we are all kind of emotionally "tuned in" to each other and we can tell when the others are experiencing strong feelings.
Some examples:
When the 13-year-old was younger, she stayed with my mom's friend while the 17-year-old and I were at school. One day at school, I sprained my ankle in gym class. Apparently my sister turned to her babysitter and matter-of-factly announced, "Mel hurt her leg and she wants you to come and get her." 2 minutes later, the school called to have her pick me up.
Last weekend, I got an image in my head of the 17-year-old's face covered in tears. I couldn't shake it, so I called her...her boyfriend had unexpectedly broken up with her.
We creep our parents out.
