Ghosts dont exist, sweetie.

Well, since I just so happen to know your store so well for some reason………….

umm…don’t bother checking the security cameras cuz you wouldn’t able to see me….i meant the burglar….trying to steal stuff….from you.

Poltergeists can move things.

I would assume that would be one way they try to communicate. That’s only if ghosts DO exist. I’m not sure if they do. Hence, I’ve never had some sort of paranormal experience. So, I’d have to say that they COULD be real. But again, I’ve never had that experience. I don’t really think your grandfather’s spirit is lurking in that stockroom.

Ghosts don’t seem to have any physical hands so how would they move stuff. And even assuming your dead grandfather could move boxes around why would he do that? Is that what you would do if you were a ghost, muck about with boxes in a stockroom?

I’m sure if you think about it a little you will come up with some more likely ideas about why things aren’t where you thought you put them.

They do try to communicate by moving things around.

Yes, to get your attention.

That is one way. But do you feel a presence in the store when you’re in there? Does anyone else feel a presence? Video cameras would be helpful for when you leave. If it moves by itself, then you have a ghost.

Absolutely. Now if you have figured out the code he is using, I will be impressed. There is a special ghost language that you only learn when you die, and it tells you the meaning of moving certain things in certain ways. It is way to complicated to explain, and I don’t know it fully, since I am not dead anymore.
However, here are some things to look for.
A box stacked on another box —- Hey, I’m doing good.
A box knocked off another box —- Your in danger
A box tipped over —- You a dissapointment to me boy.
A box floating in the air and spinning —- Boooooooo
