Something like that happened to me a few years ago, when I was in schoool.
I had to take an important exam and I just slept too much, and as one of the imagines in your posts say, the amount of sleep I was getting was too suspicious, so when I looked at my phone I saw I only had one more hour to go to my school.
Now that's okay, too bad my school was 5 km away and I had to walk to get there. I never in my life ran 5 km, but I did then, and God, I don't wish that on anyone, because if you're not used to running a lot, doing it for such a huge distance will destroy your legs. I walked like a cowboy for a week.
At least I got there and passed the exam.
Amazing story. It made me laugh so hard. I know that feel. I ran home from school the one day (I don't run as a rule) but I had to get to something (don't remember what it was) my school was about 7km away from home and mostly uphill... I nearly died.
