I should also mention that I have been visited by some ghosts before. My dad haunted me and my mum and it was funny how he said goodbye to her.
Now let me put this in order, I was in bed sleeping, snuggling with my cat and then one of my snow globes (it was a Christian snow globe with baby Jesus and the three wise men. Only reason I kept it is because it was a snow globe and a music box) started playing music.
I live near an Air Force Base, train tracks, and the highway. This snow globe has been on a shelf that's connected to the wall for like maybe over ten years. It has NEVER done that before. So I immediately knew that it was my dad. I muttered "You don't need my permission to leave dad, do what you want," Mom kept telling me to tell him to go to the light.
When he said goodbye to my mom, it was when I was at work. In the family room, she has an alarm clock that is never set to go off. My dad scared the shit out of her by making it go off. This alarm clock hasn't been used since dad died (used to be his). She told me that she yelled at him for scaring her. XD
