I know I’ve phase out for ages at a time (life is busy as always) but I’ve been lucid dreaming every night as I have been forever. Given their nature, it’s hard to call them boring, lol. But really, I don’t think anyone can get bored of it. Even if you think it’s boring for a while, fact is–you’ll want it back. You’ll want all the possibility.
So even though half of my LDs involve saving worlds from going to Hell–I’m always motivated by the pretty things I see.
It’ll be subjective for everyone, but I don’t think you’ll need to worry about people stopping their dreaming. There would have be an overwhelming reason to, I think lol.
