My favorite is the nose RC. Feels soooo great when you realize you´re able to breathe through your pinched nose!
I normally try to see if two fingers will pass through the palm of my hand because you can do it in public. If not that, then checking text to see if it changes.
Oh yeah, if I’ve been up for a while I do the “memory” reality check
Looking at hands
Fingers through palm (weirdest sensation ever experienced)
How did I get here, what was I doing and what am I doing?
Closing one eye and looking at my noose
Pinching my noose and tryIng to breathe. This one is my absolute favorite and is most reliable. If feels so crazy when it works. Kinda like being able to hold your breathe under water for as long as you want 
I have a blue elastic band that I found and turned into a ‘lucidity band’ by writing ‘lucidity band’ and ‘reality check’ on it. My cat has chewed up at least 3 of them, but I continue to find them randomly in my reality. So everytime I find an elastic band on the sidewalk or someplace it makes me a laugh and reminds me to do a reality check.
I also love to trip my mind out and do a reality check with a sense of wonder. Yesterday I told my friend it was 10:01, but then I stared at the time for a while and noticed that it could also be a pair of eyes inside a head (the 0s being the eyes and the 1s being the head) 
. She looked at me pretty weird after that one, but then I kept staring at the clock and thought, “If an alien or non-human being looked at this clock, it would ‘see’ just straight, red light and not interpret them as symbols or numbers or time…” The thinking process led me to detach from my habitual interpretation of reality. I felt pretty lucid in that moment. 
Thats a great idea ^ ^
I just lost the game. RC
