Lately, I always woke up around 430-530 without apparent reason. It's not imsomnia since I don't seem to have problem sleeping. And even after that I can easily sleep again for another 2-3 hours. I do realize that nowdays I have a couple of things pulsating in my mind, but it's not like it's bothering my sleep since I rarely had dreams about those things, instead I keep having super random dreams. I think this morning I was dreaming about a cruise ship, a baby that can talk (Stewie Griffin?), a guitar concert and a group of hawkers selling indo food just outside of a random old building. How random is that? A friend told me that I'm having jetlag. Considering that not only I constantly wake up really early in the morning, but also yawning excessively when the clock shows 10 pm, I thinks he's right. But jetlag from what?
