I checked on my kids, they didn't seem to hear it, they were sound asleep.
I called my sister-in-law, who could not hear it over the phone, but stayed on the phone with me for several minutes.
I also saw a ghost one morning that same year, while changing my daughter's diaper.
It looked heather grey and walked past my daughter's room.
The last thing that happend that night was my ponytail was being played with, behind me.
