my great grand mother passed away a few years ago, and my mom took her sewing machine and brought it to our house so she can sew, one day she unplug it (and thats very important) because she had finished her thing, and we sat arounf the table for dinner, and while we were all eating, the sewing machine (who was at the end of the table if that makes sense) started working, all by itself, without being plugged on some electricity and the button was in "off" mode, and it happenned multiple times after, we didn't get worried, we were joking about our grandma being here to check on us etc... but now, i thin k it was really weird, it had no reason to suddenly work like that! and the thing is, it only happenned when we were ALL sat around the table, eating and everytime it was unplugged. I thought maybe the machine could have kept some electricity? but i don't think it's even possible sooo... maybe my grandma was there :)
