Some dolls. I've played too many horror games to be unbiased anymore.
And Furby always creeped me out! What would you think about a toy that suddenly starts moving and talking in the middle of the night on its own?
Quote from the video comments:
I can confirm that, because I had two Furbies in my youth as 'mascots'. You sit there reading, no music this time. It's quiet - and they suddenly start talking to each other!
The stories about 'haunted' Furbies probably based on the fact that they can get deeper voices when the batterie runs out, but it seems many people don't know that. So their Furbies scare the bejesus out of them.
By the way, I mention the old Furbies, produced in the 90s. There are new ones (Furby Connect), but I don't know if they are also that 'special'.
