I wasn't sure where to post this (so mods please feel free to change if needed). Normally before I go to bed I mess around on my phone, set my alarm, and then fall asleep (but also practicing MILD). But the past couple of nights while messing on my phone, I have been hearing strange noises. It's almost as if I was in SP. Two nights ago I heard two gun shots, a child's voice, and a guitar strum. Last night I heard a ghostly male's voice say "Caroline" and and female robotic voice saying "67". I wrote them down to see if any of those noises correlated to my dreams, but none have (and I have been having great recall lately).

This has happened plenty of times, but I guess I just didn't care enough (plus I hadn't even heard about lucid dreaming and how much our minds are capable of) so now I'm just getting curious. I'm sure it's nothing serious, but would this just be auditory hallucinations I'm hearing before I fall asleep? Could I use them to my advantage in any way to help me achieve a lucid dream (as I have not had one yet)?
