My dream sign seems to be the number 5. I've seen it tons of times for example as a year, code, swam 50 meters in 50.26 sec, as a playing card... Does anyone have any ideas on how to use it to gain lucidity. I can't really do a RC each time I see the number five. I'd have to do one each time I look at the clock or the keyboard or my maths book and so on
