I hope this hasnt been suggested in another forum. (Or even stated somewhere in a site tutorial). In my real-life reality checks, I've started working my way through the entire thought process.

I'll look at some text and say to myself "This says (blah blah) I'm going to look away for a second, and if the text has changed when I look back, I'm dreaming". When I look back at the text I'll say "This still says (blah balh), but if it said anythign else, I'd be dreaming"

I'm going to start doing the same thought process for all the great reality checks that deepsleep provided.
