Actually, this is one of my fears of LDing.
I fear that if I practice too often, or get too good at it,
It will become a second nature that I can't get rid of.

I take it you don't really choose to have these LDs, right?
I wonder, is there any way to forget how to Lucid Dream once you've almost perfected it? I'd like to have the choice.

My latest dream was a truly wonderful mix of being both conscious and not conscious, and those are usually the best types of dreams. You drift in and out of knowing you are dreaming, so you still experience the emotions and connectivity really well, but you have more of a say than normal too.
