Lucid dreamers, what part LD takes in your life ?

I’m not a lucid dreamer, I got some of them and I was so amazed by their reality (more vivid than real life) that I started to search to get more of them.

I want that real lucid dreamers, those that can get one when they want, tell me what part it took in their life.

-does it become just a curiosity ?
-or a playground ?
-or the indispensable way to know what your subconscious want ?
-or the second half of your life ?

What if you lost the ability to lucid dream tomorrow ? Do you consider it would be as bad as losing one of your sense ?

For me, lucid dreaming is merely a way to relax after a long day. The ability to do whatever you want without any inhibitions really takes the stress right out of you. If I lost the ability to lucid dream, I would be extremely disappointed, but I would eventually get over it. I mean, I have gone months without having a lucid dream before, and have almost completely forgotten about it. So it wouldn’t be too big of a deal.
