Your mind is the scene of the crime
I wish we could screenshot inside dreams. If I had the choice to pick my next superpower, I'd choose dreams superpowers, like Cobb in Inception, to do whatever I want inside dreams. Imagine, being able to capture as a picture whatever comes across your dreams, capturing these moments where you wished you're not dreaming. If I could do that, I'd have pics of me scoring in a world cup final game at 90' minute, I would have OTHER pics of us together, I would have some recent pics with people who died, who are far right now and seen only in dreams. Some people may find this idea/wish weird, unuseful or simply they'll think that value of dreams will decrease (the lack of something makes him valuable), sorry to say this, but they doesn't have some awesome enough dreams maybe! After all, I'm remembering the definition of dreams according to Freud, and how Inception ended, and I look back to what I wrote above, daaamn I wan't to laugh and cry at the same time!
