I dont actually believe in ghosts myself,well not in the sense that they are concious and able to make actual,meaningful decisions,However,I do believe that energy remains in places,very powerful energy capable of the types of incidents that you describe.
dont let your mind play tricks though,i seriously doubt whether yourself,wife or child are in any peril.the most harm from these incidents is done by ourselves,as we tend to read more into these occurances than need be.please do let me know if anything else happens.
