This happened when I was in high school. Me and my brother were the only ones at home in the morning, as our parents had early shifts at work. So my mom usually woke us up by calling us on the house phone. This particular morning, this happened:

• My alarm clock on my phone went off like 5 different times, and I somehow snoozed it forever, or turning it off, without even remembering it
• My radio clock went off, snoozing or what? Dunno
• My mom called on our house phone, like 5 times (with probably 10 rings each time)
• My brother came in to my room to wake me up
• Still no waking, I can't remember any of this, but everyone had presumed I was getting my ass out of bed at some time, so they thought I was at school
• My dad had his lunch at home, walking past my room several times
• At 1 pm my mom git home from work. The hallway is right outside my room
• She vacuumed the hallway!
• Our dog was everything but quiet
• The phone rang a couple of times
• My brother came home from school at 3 pm
• They'd prepared dinner and was ready to eat, and wondering why I was still at school
• My brother went down to my room to check if I was still there, and I FINALLY awoke
