Dream argument
The Dream argument is a philosophical idea suggesting that it can be difficult to distinguish between waking life and dreams. Since dreams often feel real at the moment, it raises the possibility that our entire experience might be a dream or illusion. This challenges the certainty of our knowledge about the external world, prompting questions about what we can truly know. Essentially, if dreams can mimic reality perfectly, we must consider whether our perceptions are always reliable or whether we might be mistaken about what is real.
