Hmm, now I wonder why my sim children have been so relatively unattractive to monsters then. Possibly the chance of finding one could be trait based, or maybe more expensive beds have fewer or higher quality monsters under them (yeah, that makes no sense). :/
Edit: Okay, got it (I think). The base chance of finding a monster under the bed is 60, reachable by Retuner. The base chance of then being terrified is 50, with a 20 percent chance increase for those who are Coward, Neurotic, Easily Impressed, or Supernatural Skeptic.
