Do You Miss Imaginary Friends From Sims 3 and Wish They Would Add To Sims 4

I've never played Sims 3 but I've watched some let's play videos. I saw one of those things and it was so creepy, it was like from some horror movie. If they will add anything similar to Sims 4 I hope it will be much less creepy. I don't want to have nightmares from playing Sims. :#
