 That theory's been tested in different ways. In one study, researchers followed students who were preparing for an exam, and they found that the ones who had nightmares about exam day, like they were running late or they forgot the answers, that sort of thing. The more dreams they were having like that, the better they actually performed. So, you know, you might dream about missing your alarm, and then you think, I'm better set to. Another theory is that dreams can be a form of wish fulfillment, the place to get what we want. And then there's an understanding that dreams can help us process our emotions.
