Why Vivid Dreams Aren't a Sign of More Dreaming — Just Poor Forgetting
Sleep experts explain that vivid dreams during restless nights are not a sign of increased dream production but rather a failure of the brain's forgetting mechanism. When sleep is interrupted, particularly during REM sleep, the brain fails to delete dream memories before waking, allowing fragments to be encoded into conscious memory. The phenomenon explains why bad dreams feel so real — the prefrontal cortex, which provides logical context, is offline during REM sleep.
