For all intents and purposes I kind of felt like a cat when I slept. My bed felt like a cloud, and I had the quietest company, and I didn't make a sound with my towel wrapped around me ever so comfortably.
I think the most I've ever slept in one go was 36 hours, which was when I was trying to align my sleeping schedule for I don't even know, since I didn't go to school then. I think I woke up for like 5 minutes and had my mother give me my medication with my eyes covered so my body wouldn't start making serotonin. The most I've ever stayed up in one block was 60 hours (2 1/2 days), ironically. :p
