I've noticed that in almost all my lucid dreams I don't do reality checks. It seems as if perhaps I'm so convinced by the quaintness of my dream environment that further checks are unnecessary; I'm certain I'm dreaming.

I find reality checks trite, and not offering much benefits that I might use in an everyday waking state. For example, counting my fingers, and incessantely scrutinizing them.

Maybe the questioning during waking hours itself lends to ld's, but I prefer to replace reality checks with mindfullness, in which I would pick one thing to focus on and tend to it for about 20-30 seconds. At least this would give the benefit of learning a little more about my surroundings.
