Wow, that's great! I'm studying French right now and I WANT that to happen to me. While it may be a problem for someone who has to go to a real job the next morning, I have to go to French class instead.
Could you share with us your specific technique and procedures that led to such fitful nights? I've been photoreading French dictionaries and books for a while now, but aside from a few dreams I've had nothing come close to what you've experienced.
thanks.
