Sageous, sorry, I'm a bit confused.. You say that I should only ask the question "is this a dream?" and do memory checks with questions like "where am I, where was I" etc at separate moments, not to combine these with RCs. But in the OP you said

For instance, when practicing reality checks during waking life (and everyone should be doing that!), don’t just confirm that the clock didn’t change, or that your hand still has five fingers, but, when you're done checking your state, take another moment to remember exactly what you were doing say, fifteen minutes earlier.
Wat Maybe I'm confused cause it's late and I need to go to bed but it sounds contradictory to me right now..
