It seems like we know a lot about the continuity hypothesis of dreaming. So why continue to study this model of dream content?

Although considerable research supports the continuity model of dreaming, central questions regarding the nature and extent of continuity between dreaming and wakefulness remain unanswered. For instance, it is still unclear what particular dimensions of waking life (e.g., physical activities, cognitions, emotions) are most robustly associated to specific dream content. Similarly, relatively little is known about the extent to which people's dreams are reactive to individual differences in waking state and trait variables (e.g., daily stressors, personality, psychological well-being).  And, of course, there are many other models of how dream content relates to waking-life dimensions, including in terms of various kinds of learning, emotional regulation, how people react to different kinds of trauma, and so on.
