[insidious]

Ever had hypnic jerks? I've had it happen a few times, but it is also similar: https://sleep.org/articles/hypnic-jerks/

No way! I've always wondered why the fuck I do that. They happen pretty often, maybe once every three months or so. I don't really mind them, the feeling of falling is always kind of cool, but it never ceases to surprise me.

I've had these since I was a kid, never really thought much of it. Just thought it's something that happens to everyone once in a while.
