You know, this is a good question.
Googling it would ruin the fun, but I’d assume that it’s an evolutionary thing so you don’t decide to go to sleep in an unsafe situation and get yourself eaten.
I bet you’re right. It also probably has to do with shutting down/pausing brain function to enter our “sleep mode”. Though I have no clue what I’m talking about so take it with a grain of salt
Or dance to sleep
Falling is dangerous. I prefer to drift off.
So, here’s my thought:
Maybe the reason has to do with how we wake up. Our bodies must hit a certain state in order to sleep, and in order to exit sleep. If sleeping were a voluntary action, we’d either need to remain partially conscious, or else we’d go to sleep forever. If our bodies and minds have hardcoded conditions for sleep, however, this will never be a problem under normal circumstances.
