Although maybe it's very unlikely you could be on to something. I used to have many experiences like this when I was younger (sounds like you're talking about sleep paralysis) and I remember loud buzzing when I also took some medication to help me relax. When I was in this state I had vivid hallucinations and it often felt like sound was louder. I posted here about hearing my bad phone charger, and I've actually had an experience of sleep paralysis coupled with that once which made it sound louder than it really was in reality.
