Not hearing my alarm

[Muggler]

So recently, my alarm hasn't been waking me up. It is still set for the same time, and the same volume it always has been, and it has always been waking me up. I think it might be because I go to bed late and fall into a deep sleep. I will start going to bed earlier, any other suggestions?

It probably is because you're sleeping late. If you sleep later, you tend to, of course, wake up later. Therefore, you fall into a deeper sleep. This is all my conjecture, so anyone is welcome to prove me wrong, but I believe that the more sleep deprived we are, the deeper we tend to sleep.
