Sam and Colby’s board game

So I woke of from my sleep to hearing this weird beep noise then talking so I didn’t think much of it then I hear it again coming from the board game now keep in mind Ive looked through everything in it and didn’t set anything up cause I just have it for decorations but there’s a device called the ghost comm so am I going crwzy or does that randomly make that type of noise without batteries in them pls reply and answer what it could of been lol
