IDEA for Sims 4 expansion pack: A Dreaming Expansion.

i like the option if maybe you can advice other sims about how to make peace with yourself and/or others and of course an another option to ask other sims for advices about how to make peace with yourself and/or others

and maybe similar to lovestruck you can have a career like some kind of counseling but it's with like friendship and enemies instead (rabbit-holes career) about how to deal with the situation and how to make peace for those who have deceased

you can like enter the dream/secret world or by interracting with the ghost in the residental worlds, it can be both

and if you have other packs installed you can talk to deceased animals too

it's most likely the imaginary friend might come out with this upcoming Expansion Pack but i do like to add maybe children can have some dreaming aspirations like maybe "i dream to become" (you can fill in)

we can perhaps have a personality trait called "absent-minded" (in my another comment i mentioned about "the dreamer" personality trait)

and maybe as a teen similar to "Life and Death" with creating a will you can create a career you want to go with (it complement with "Discover University" very well) so this way it's still dreaming related

i finally know something else: a career or freelancer you get to advice people to life your dreams no matter what and if not you can comfort them and try to cheer them up
