A little while ago, when i first learned about lucid dreaming, i came across a number of websites that said one of the things you could do in a dream is personify your subconscious. Basically you could talk to yourself without any barriers and get some surprising answers. Anyway my question is, if you were able to somehow "meet" your subconsious (i use quotes because essentially it is you you're meeting), could you ask your subconsous to hold you in the dream, thereby prolonging it indefinitely? I'm nowhere near experienced enough to have the control to try this but if someone with more experience could try this and report back it might prove interesting.
