There’s no real reason for you to remember falling asleep. Its not a critical item that would require a memory slot, basically, so you have evolved to shut off the part of your brain that stores memory at that point.

I recognize when I’m falling asleep but of course not the moment when I pass into sleep. I start thinking things that don’t make sense, and realize that this isn’t something that would occur and then have the thought “ah, I’m dreaming.” and then boom lights out. can’t remember anything after that.
