So, your saying that the people you see/hear are not actually there right? Just making sure, anyway, that sounds like HH to me, I would get to exactly this point when I used to try WILD'ing a lot. This phase of hearing people talk and almost seeing things was immediately followed by a loud ringing noise in my ears, then SP, and finally a full LD if i was able to stay calm enough to transition. My advice would be to simply remain calm, it seems like you are getting way too excited when you hear these voices, but remember its all normal as your conscious mind is about to fall asleep, if you are able to remain calm but at the same time slightly alert, you will soon transition into a LD, good luck!!
