Yesterday, I got home around 00:40. I changed clothes, brushed my teeth and got some other small things done before finally going to bed around 1:20 or so. I fell asleep pretty much right after this. I was sleeping really deep, when I woke up. I couldn't settle. I'd just keep moving around over and over. I look over at the clock to see how much time I had slept. It showed me 1:30 or so (apparently either 1:27 or 1:37). That wasn't possible! I mean, I really slept more than that. I double check it, looking at the projection (that clock has a handy laser projection feature, allowing me to see the time without getting up), but it's the right time. I'm wondering if somehow the clock got messed up, so I think about getting up and checking my cellphone. I stay lazily on  bed, until I fall asleep again. I wake up on the morning, at 7:30, and notice time did pass normally on the clock, leading me to believe the whole strangeness from before was a false awakening. Everything was as vivid as real life before, so I just couldn't tell the difference.
