Whilst doing a reality test, a lot of people think about what they did during the day to test their memory.
Doesn't this distract you from being mindfull since you'd have to think about the past instead of the present? Isn't a reality test all about being present and about being critical and investigative of your current surroundings and perception?
I don't think this necessarily distracts from being mindful, as you are only visiting the past to do a critical examination of the present. For me, it basically means that I'm investigating my spacial and temporal surroundings, so to speak. This is just such a crucial element of dreams: you mostly get thrown into a situation, without context, so an investigation of "How did I get here?" can already tell you all you need to know.
