I find it that doing reality checks helps put you into that lucid dreaming mindset, whether they carry over in dreams or not. As long as I do at least a few during the day, that shows that I have dreaming at the back of my mind.

The desire to have lucid dreams will then show up in dreams, while not necessarily the reality check itself. It will be an extra point if the RC is also done upon encountering a dream sign. All in all, I find doing these to be beneficial .
