Where wild minds come to rest
I never mix daydreams with the real world - there is no connection. When I read your post I thought I'll try, but for me it is not possible. I can't talk to my dreamworld, my charakters won't talk to me. I can't even mix the different storylines. MDD is also no topic in my daydreams.
Sometimes, especially if I can't make a part of my story work well, characters can criticize me. 'Well I'm not even real anyway!' in a joking manner.
Most of my daydreams involve the real me in a near future so these days I am daydreaming about sharing with someone or a group of people how I managed to stop daydreaming!
