I'm constantly trying to think of new reality checks or variations on existing RCs. Like atkins513, I've been wondering if my idea for a movement-free RC would work.

It would revolve around your awareness of itches. At any time, I've realised that there are a number of itches on my body that are below the threshold of my awareness (if you think about this at night when you're trying to go to sleep it will drive you mad, btw ) Two questions:

Do we still feel these below-threshold itches when dreaming?
If we attempt a WILD that ends with the "false awakening" scenario, do the itches on the body "die" thus being an indicator that we've entered a dream?

The mind being a clever thing, it may well be the case that it can accurately replicate the sensation of itches in dreams - or still perceive real itches on the sleeping body - but I'd like to ask for thoughts on this.
