Yes, I've had this happen to myself once or twice.

This is what happens when you set it on your conscience that you profoundly want a lucid dream. What this will cause is for you yourself to imagine what you would do in a lucid dream, what it would be like, etc. If lucid dreaming becomes a deep interest for you, and you intently seek to have them, you may find yourself simply dreaming about lucid dreams, whereas the actuality of it is infact, just another dream; dreaming about a lucid dream.

It's hard to over-come this step, but the essential priority is that you don't want to be trying to hard to lucid dream. If it becomes simply a profound interest or hobby, then it will be harder to have. This is because your subconscious is obsessed over the concept of the lucid dream, instead of trying to reach that level of comprehension.

Essentially, what you want to do, is try not to think of lucid dreaming too much. I know in order to remember your dreams, you have to consciously tell yourself, "I'm going to remember these dreams" (this is you coaxing your subconscious) however, if you think, "I'm going to have a lucid dream! Yayy!" then you're going to have trouble.. So, you have to depress your excitement for a lucid dream. Anxiousness and anticipation are your enemy. Test your patience in wake with whatever means you find test your patience best.

In order to test you patience, you must first understand how you can do so. It isn't something to simple as siting around waiting for a bus, it's that checking your watch every 5 minutes for the bus. These are little quirks that subside our anxious conscience whereas, in reality, knowing the time, doesn't help the bus come any quicker, and complaining about it, as we all know, also doesn't help. This is what I did, I simply stood still and waited for rides, or whatever deadlines, and fought looking at the time and attempting to subside my impatience.

Hopefully I've been enlightening
