Just had a minor success: questioned reality three times this evening due to walking through doors, and a moment ago thought: "I am exceedingly sleepy, that's because I took NyQuil earlier this evening unintentionally when I planned to take Mucinex. Which is exactly the type of excuse that a dreaming mind would come up with, and this mental fog is just like in a dream." While a reality check showed that I am probably awake, but I think this was a good start.
