Had A Very Interesting Dream.

As i have allready posted in the "newbie" section. I have always had the ability to fully controll myself and surroundings in any dream i wish.

Anyway Last night I really focused on staying In the Dream and keeping controll of it. I effectivly Lived Out a complete Day withing My dream. As i Woke up it was the middle of the Night and I had only been in Bed for 3 hours.

Would it ever be possible to Live out Weeks/Months or even longer Within A Single Dream lasting only over One night?
