ELI5:Why do we forget our dreams so quick?

Even if i have a really memorable dream i forget it in about 10 min after i wake up,why is that?

Your brain just isn't set up to remember a lot of your dreams. Your memory bits essentially shut off during the REM sleep stage, which is when most people dream. However, if you dream *outside* of REM sleep, you are more likely to remember dreams because your memory bits are working a fuller capacity. There is also evidence that you are more likely to remember dreams that have some sort of emotional connection to you/your life.

There are also stages of sleep where you are more awake than unconscious. It's common to have what are essentially daydreams. Of course, these are also more likely to 'stick' in your memory.

There are a lot of questions about the legitimacy of claims like lucid dreaming and learning to remember dreams. So...be mindful about evidence. Remember that shutting off memory during REM sleep is a biological process, not necessarily something you can willfully alter. A lot of dream training/remembering bs comes down to messing with your sleep stages, and messing with sleep isn't good for your health and well-being.
