Sometimes I have this problem where, during a lucid dream, menus will show up in my field of vision and make me forget I have limitless options during any situation.

For example, this morning I had a lucid dream where I was being tracked down by a skeleton. When it finally arrived, a sort of weapon select screen came up. I was allowed to pick between about 20 weapons. This made me lose my lucidity by forgetting that I could do whatever I wanted in that situation, and everything felt more like a video game than a dream.

In another lucid dream, I was trying to summon certain objects, and all of a sudden i get the Scribblenauts menu, where you have to type in an object name to summon it. Again I forgot that the menu wasn't necessary, and lost my lucidity while trying to figure out how to type in the name of an object.
