It's fully new addition to a game but for me it's sounds very cool.
Add various types of ghosts:
1. Ghost encounters like raiders/drifters/visitors
2. Ghosts of colonists who past away (friendly, not)
3. just random ghost guys who spawns in the dark places (I like this)
Interactions:
1. Ghosts can startle people (various moods penalties)
2. Make dirt/break things/start fire
3. Colonists can exorcise them
4. Friendly ghosts can help with bad ones/startle raiders/give a mood bonuses
Something like this.
(ghost hunters, ghost traits and backstories, interaction with "incapable of scary" is obvious)
Also, visually ghost it's a normal person but with transparency and/or in grayscale.
