Studies of large samples of dream content collected in the laboratory as well as outside the laboratory show that dreams mostly occur in commonplace settings, contain a large number of familiar characters, and revolve around family concerns, love interests, and activities engaged in during waking life. In fact, only a minority of dreams involves unknown characters and activities that are out of the ordinary. So for the most part, dreams can viewed as a reasonable simulation of waking life characters, social interactions, activities, and settings.
