My apologizes for my interruption in your dialogue but I'd like to add my opinión.

I'm totally agreed with Snap.
It sounds to me as the dreams, only that in day dreaming we are asleep.
It has to have a psychological meaning, as dreams.
The Grey Wolf, Snap gave you some suggestions about what could mean your fiction lifes. Obviously, you are the best to know or discover what all these lifes mean to you. These things are very personal so you are the right one to test your day dreaming.
You are compensate your lacks in your real life.

How can you stop it? I will tell you my experince. I went out of it by doing real things. I had to find a balance between what I wished and what I had.

I hope you find your way.
