ouija board smashes 2 glasses

hey everyone, recently i was discussing with my mum about ghosts and jokingly said i wanted to try a ouija board im 15 btw she suddenly got very intense and told me not to. i asked why not l and she responded with this story. when she was a teenager back in the 1970s to 80s she and a group of freinds decided to jokingly do a ouija board. they didnt have the eyepiece thing ( udk what its called) so her freunds grabbed a glass from the cupboard but as soon as she ppaced it on the board it scattered. her and her freinds quickly cleaned it up and shrugged of what happened. they went and grabbed another glass to try again and once again it smashed my mym then told she felt something in the room with her she cleaned it up and put away the board and she never touched it again. i left that talk feeling spooked but whats your opinion (edit. apparently she ran out the house after the second smash) xD
