Exploding Head Syndrome 

A common sensation where one perceives the sound of an explosion, the feeling of a brick hitting their face, or another abrupt sensory impulse that jolts them awake, only to realize they were imagining it. This typically occurs as one is about to fall asleep, when one begins to dream before their body can enter a state of nocturnal atonia.

1: "...gah!!"
2: "Holy shit...! You good, babe?"
1: "Ah... yeah, I'm fine. Just an instance of exploding head syndrome."
2: "Well, good thing your head didn't actually explode, eh?"
1: "Heh... definitely."

Exploding Head Syndrome 

The sensation of hearing a very loud noise in the middle of the night, typically when half-conscious. However the sound never actually happened. Sounds range from explosions and gunshots to even human noises. Rarely, there is a visual phenomenon accompanying the noise, such as a flash of light. The exact cause of the syndrome is unknown.

I woke up at 5am from a loud crashing sound, but I think it was just Exploding Head Syndrome!
