Woke up and was too tired to differentiate times?

I leave for school at 7 AM. So I normally wake up at 6:45 AM. But last night, I woke up in the middle of the night at 12 AM. And I was too tired to realize it was 12 not 7. And I was like "****! I'm gonna be late for the bus!" So I threw on some clothes in the middle of the night. Got my sweatshirt and everything, and left the ******* house in the middle of the night. Walked up to my bus stop thinking I was super late. I got down there, and then I realized. I didn't leave at 7. I left at 12. And I had 7 ******* HOURS to get to school. So I walked back and passed this creepy guy who was wandering around outside. And then I got home, and my parents opened the door and kept asking me questions. I quickly told them what happened but I also didn't want to talk at that time. I was upset with how stupid I was. I went up to bed and slept. Do you know what the hell happened? Did I sleepwalk or something? I haven't been able to talk to my parej a about it since I'm writing this on the bus to school wih my phone. Thanks!
