Regarding bizarre dreams, which statement is supported by selection bias?

• A. Bizarre dreams are common and highly memorable
• B. Dreams are rarely bizarre, and we notice them immediately
• C. Dreams are rarely bizarre, but we often do not notice it until we are awake
• D. Bizarre dreams are never remembered

Answer: (C)

Selection bias in dream recall means we disproportionately remember and report dreams that feel unusual or striking. Because bizarre dreams stand out, they are more likely to be remembered and shared, which can make them seem more common than they actually are. In reality, most dreams aren’t bizarre, and the oddness often isn’t noticed until we’re awake and can reflect on the dream—memory then highlights the strange parts. That’s why the statement that fits best is that dreams are rarely bizarre, but we often do not notice it until we are awake.
