In my attempts this morning, I discovered that, when I am attempting WILD, somewhere within my HI I reach a point where I can literally hear and feel my mind hit a kind of “switch”… After that, so long as I hold still and maintain focus, I’ll always at least get past the WILD transition into my dream state. I don’t know what it is, exactly… Maybe just the sensation of my brain releasing some sort of chemical or signal that eventually induces REM sleep?
Anyway I was wondering if anyone else has any signals that sort of tell them where they are in the process of successfully entering a dream like that? 
Post whatever signals you experience when attempting to LD!
