Sometimes when trying to fall asleep, I am jolted by an INCREDIBLY loud explosion in my mind. It sounds real, but somehow I can tell my mind created the sound. It just seems to... come from inside. I can't really explain it. This happens once every few months or so and last happened a few weeks ago.

I searched and this is the only thing I found, but no one replied:

"This happened a long time ago. I don't think it relates to dreaming, so I'm posting it here. It was early morning, and I was in the half awake/half asleep (actually mostly asleep) state, and all of a sudden I hear a defeaning explosion. (I wasn't dreaming anymore, but I was in the this semi-state) I jolt awake with my heart racing. My first thought is lightning must have hit that house, but it was a bright sunny morning. My second thought was that maybe a bomb dropped in the area, so I run outside, and everything is ok. My third thought is, maybe a TV or Radio was on in the house, but everything was off, actually everyone was still except for my mom who was in the bathroom. I never found out what that was. It happened years ago and it's the only time in my life something like that ever happened. It was not like ordinary Sleep-Paralysis with booming sounds... this was just a defeaning explosion noise out of nowhere

Anyone have anything similar/random like this that was maybe actually connected to something? "
