Here’s one I stole from another forum. Tell us a real or fictional ghost story!
There's a young girl home alone, reading ghost stories in bed. Whenever she scares herself a bit, she dangles her arm off the bed, & the dog who is lay under the bed licks her hand so she knows she's not alone. Eventually, she goes to the toilet, & is comforted by the sound of the dogs footsteps following & waiting outside the door. She then turns round, & written on the mirror is 'humans can lick too'.
