I've heard of people who can extend their lucid dreams to days or even years. This must surely be the holy grail for many lucid dreamers, including myself. Anyone here able to do it?

What I want to know is if these dreams are completely indiscernible from real life years. Is there something which doesn't make them quite as real? How about as original, with all the weird and unexpected happenings that you'd get from real life?

Since you're experiencing the lucid dream for years, do you get to sleep 'inside' the lucid dream, or are you awake all this time for many years?

Finally, do you experience a change of personality after you awake? Do your family, friends and relatives see you as a different person?
