We realize that the story is not a dream since we finished the book - Gregor dies as a bug, and doesn't wake up back in his human form. But there are many dream-like qualities in the stories that relate to the story-reality discrepancies. For example, with Gregor's three doors, there are instances when multiple people will be talking to Gregor from outside the room, but all through different doors, which relates to dreams of sound echoing all around you.
When Gregor finally reveals his bug-self to his family for the first time, they all automatically know that the bug is Gregor, not that it has eaten or disposed of Gregor. This is a great example of 'logic' in dreams - it doesn't make sense in the real world, but it somehow does in dreams. Other examples of dream logic include Gregor's single-minded devotion to his family (even after finding out the money he earned was saved instead of used to pay off the debt), the boss coming to Gregor's house to check on him, and that the mother, who was so frail because of asthma that she couldn't make it across the house in one go, only had her asthma portrayed when Gregor came out, right before he died.
Can you all think of any more discrepancies or examples of dream-logic?
