I didn't think much of it as it only happened once and I was pretty high. Well earlier today I decided to use my vaporizer again to kill the rest of the weed that was left over. I sat in my room putting eye drops in when I heard sort of a mumble from behind me and I jumped and dropped the eye drops. My back was about 2 feet away from my wall, and nothing was there. Well I finished putting the eye drops in, and I decided to play guitar a little to relax and get my mind off of things. I was playing when I heard my Dad's voice (clear as ever, definitely his voice, and it sounded really close, not outside my room or anything, like he was right in front of me) say 'How was school?' and I stopped playing and looked around, nothing still. I left my room and asked my Mom where my Dad was, and he was still at work.
I'm not sure if I'm over thinking things and imagining this stuff or this is real. Any help guys?
