Because every ghost isn’t as friendly as Casper.
Encounters with the paranormal aren’t uncommon, but some ghost stories are weirder than others.
Maybe one night you saw a bloody girl behind you while looking in the mirror, but when you turned around, no one was there.
Perhaps while watching TV alone, you suddenly felt something hugging you tighter and tighter until you couldn’t breathe.
Or maybe late one night while you were alone, you heard footsteps and someone whispering upstairs.
