So sorry for posting here, no idea what topic to post this in and just wanted some answers fast!
I just drifted off to sleep on the couch around 30 mins ago (late night last night and busy week!) when I kept hearing a woman talking, really loudly! It was starting to do my head in as I was just drifting off when she'd start up again. Eventually I must of dosed, I don't remember if I was dreaming but I could still hear this damn woman even though I 'knew' I was now asleep. Eventually I realised that it was coming from the hallway and only getting louder.
I awoke immediately realising it was coming from my own house. I listened for maybe 3 mins or so to hear who on earth it was as I was worried it could be an intruder etc... then realised it was ME! Yep, you heard that right and nope I am not crazy. It was my voice 

I couldn't make out any words which is weird because it was so loud and sounded as though I was literally in my hallway having a full blown conversation with someone yet couldn't hear any responses even though 'my' voice paused to let the other talk. SO FREAKIN' WEIRD.
I'd like to think I'm a grounded person so can anyone offer any opinions unto what on earth happened? Scientific or otherwise? I am a Christian and do believe in a spiritual world however I am fully ready to admit it was probably something weirdly scientific in nature.
So AIBU to be really freaked out and have no idea what just happened?! Please offer me some suggestions. This is NOT a troll post, this genuinely just happened.
P.S. as soon as I got the courage to get up and investigate the voice stopped immediately and consequently, there was no one in my hallway and the door was locked
