I never really believed in ghost and things but, i do now.
I work at a supermarket and in the warehouse we have a big walk in cooler and the door to it randomly opens. I know not much but there is more. One day I was cleaning the bakery and boxes that wear on a shelf flat, not tilted or anything, fell. So i walk over there to put them but and for a second I got really cold but only for a second. Bread also falles off our selves and I seen it just fall. Other things have happened like the front doors just swing open and close. Other workers have told me of other things also. The owner also believes that there is a ghost.
