A spell list for fake hauntings? Next you need to make a spell list "Mystery Mastery" for Those Meddling Kids!
Duration for poltergeist seems low for the effect. It's pretty innocuous, I'd make it 10 min/lvl. A shorter duration would make sense if the objects are striking people.
Disturbing Thing should specify what happens if you make the fear RR.
Wavering Light should give a penalty for lighting.
