> if there was anything to remember from your dreams, you'll lose it by doing this. Dream memories are extremely fragile
I've always had a natural ability to remember my dreams. And one of the most curious things about my dreams is that I can recall (as in right now) dreams I had decades ago. I can often remember them until late in the day. I can also know when I had a dream I already had years ago (it happens often). It's almost like a deja vu.
I never had a dream diary, but I would like to make one just to find these repetitions, connections, relations, etc.
