Didn't get to sleep until after 6 AM

Don't know why. I had to put blankets and stuff all over my windows to block out the light, as the sun was already coming up. It was like some sort of awful torture, knowing that everyone else would be waking up in a few short hours and then they'd make noise, wake you and the whole situation would become immeasureably worse.
Now I'm knackered. Anyone else not sleep well last night. Rubbish isn't it.
