Literally recently, were added, "sleeping events",nightmares of the character that he can dream, if he has a negative moodles.
Browsing the official russian group of PZ,i have found this .
My suggestion is :
1. Why not add good dreams for the character, if he has a positive moodles? ( well fed for example )
2. Adding a soundtrack for "sleeping event" dreams.
3.Also, in my opinion, i think,it would be nice to have positive versions of bad moodles,that will be give a
lil'bit boost for healing and speed of dragging items
