Yeah, I definitely try to question my reality and if I'm dreaming or not when I do them. I've been looking at my hands to make sure I've got 5 fingers and checking digital clocks... Plugging your nose seems to work really well for a lot of people so I think I might start adding that in a lot more frequently, just seems like it won't be as easy since I have to go out of my way to check rather than just catching a glimpse of my hands or a clock.
