There is a scientific reason for this. Prepare for minor text wall.

When you fall asleep, your brain erases temporary memory and “closes” permanent memory so that nothing can be stored to it during sleep. This is also the reason you can’t remember what you did a few minutes before falling asleep. Therefore, your dreams are stored in temp memory and you can only remember them for a little bit after waking.

Don’t quote me on this, I found it somewhere, and my somewheres tend to be pretty reliable, but I’m too lazy to fact-check. Feel free to downvote if wrong.

I hate it when the dream is so good and lucid, but you wake up and only remember how nice the dream was rather than what you experienced.

I hate that this basically is the first step of learning to make your dreams lucid. "Write down your dreams to find patterns" - Okay sounds easy enough but every morning I'm like oop I forgor

What's worse is if it's a horribly bad dream I'll remember every detail.
