This is the evil part of your brain in the morning that tries to trick you into sleeping in. It often attempts to fool you into thinking you've already woken up by making you dream about getting ready for work.
Dude, I'm late for work! I think Sleep Brain turned off my alarm this morning, cuz I don't remember doing it.
