I would like to understand and know what I am experiencing, but not sure what it falls under. A few times a week, right before I wake up in the morning, I experience a body-vibration, loud noise (few seconds), or a loud boom which lasts a few seconds, it feels like an earthquake to my body or I vibrate and then I wake up. I am not afraid, I can move, not a paralysis, but I am not fully conscious. I look around and check my 4 dogs on the bed, and they don't recognize it and are sound asleep, so I know it is not an earthquake or a noise in the building/house. I usually lay back down and go back to sleep. This happens a lot so I want to find out what it is and how to learn from it. If you could help me put a name on it so I can read up.

Thank you! Meredith

I think this is just a half-way stage you experience between sleeping and waking, when your brain isn't exactly sure if you are asleep or awake. Some people hear a loud noise or their name being called before they wake up.
