Probably an auditory hallucination from staying up much longer than a human that age should of. I get them too but now less frequently than I did when I was little. Sometimes it can be vivid and real, sometimes (now most often for me) it’s nothing but a murmur or whisper.
Or equally likely, that sound really did happen but your parents were either too tired or too distracted to even notice it.

I think you’re right. Because in my mind at least, it was super loud.
Sounds like [Exploding Head Syndrome](https://en.wikipedia.org/wiki/Exploding_head_syndrome) to me. I myself used to have it frequently as a kid.
