Hello and welcome!
Looks to me that you´re describing self induced sleep paralysis, rather than a state of lucidity. It is however totally possible to use the WILD technique during that state, if you find a way around the high pitched noises and the uncomfortable sensations. When i do it, i usually start seeing irregular patterns while my vision slowly fades to light grey or violet. My body goes numb, and about then, i'm able to enter lucidity.
