You do not remember dreams because your brain is busy. It’s a classic trade-off, really. Your mind is so occupied with the critical work of memory consolidation that the dream itself just slips away.

Meaning
Forgetting your dreams isn’t a memory failure; it’s a sign your brain is prioritizing long-term memory storage over dream recall.
Explanation
Think of your brain’s filing system. During deep sleep, it’s transferring the important memos from the “short-term” desk (the hippocampus) to the massive, permanent “long-term” filing cabinet (the neocortex). This process is so resource-intensive, so all-consuming, that the brain can’t simultaneously create a perfect, lasting record of the dream narrative itself. The dream is almost like the background noise of this massive data migration project. It’s not that the dream isn’t happening—it’s that the recording function is turned off to free up processing power for the more vital task. So when you wake up struggling to remember, you’re not failing; you’re actually witnessing the after-effects of a highly efficient, successful night of cognitive maintenance.
