ELI5: Why do I often wake up from a dream right before "the good part"
gpt
You probably don't. You dream many times during the night, and you're only likely to remember the dream you were having when you woke up.

Furthermore, dreams quickly fade unless it was a particularly vivid dream or one that you make an effort to remember by writing it down or continuously thinking about it.

If you woke up during a mundane part, then it's not a particularly vivid dream and it's not one that you'd really make an effort to remember, so it will quickly fade from your memory.

The end result isn't that you often wake up from dreams right before "the good part," but rather it's only such dreams that you remember waking up from. All the other dreams have been erased from your memory.
