yeah.. I hate it when I don't remember my dream.. that's most of the time.. but sometimes I remember..
I had a handy method that seemed to work for me, if I woke up in the middle of the night after a dream, I'd drink a sip of water (without having to get up, just a glass on the nightstand) and go back to sleep again, then when I'd wake up in the morning I'd take another sip and somehow that repeat took me back to the moment where I kinda half woke up, and I'd remember the dream
I've never had a nightmare after a scary movie, luckily
