While it wasn't last night, about a week ago there were these drunk people yelling outside for like, at least an hour. x_x I could still hear them after closing my window.
When Pokemon X & Y first released I couldn't sleep that night because I was too hyped up & was excited about playing it so I stayed up a couple of hours playing Pokemon X cause I was so happy I could finally had it I couldn't wait to play it! XD
Last time I struggled to sleep, it was some obscure unsolved mathematical problem. I decided to give it a go - and, unsurprisingly, it remained unsolved!
When it's too hot and I can't cool down in any way possible, because even if I manage to fall asleep my dreams intensify immensely and I re-wake all sweaty two minutes later.
Staying up to late reading the Wookiepedia about Leia Organa as I'm curious what was going on between all three Star Wars movies. Came to find out a lot of what she did was just running around & trying to fund the Rebellion once Allderaan was destroyed.. o_O;
Well, I was asleep until around 3 am, after waking up then, I couldn't getback to sleep for a few more hours, nothing was really preventing me from sleeping, I just wasn't tired.
The computer is one of my mortal enemies. Sometimes I don't even do anything and it suddenly becomes 12am or later (on college days)/2am or later (holidays).
Drawing at times knocks me into 12am territory, unless I persist with a particularly major sketch and I go into 1am territory.
If I somehow get my hands on other electronics during the night (I get caught out and get it sanctioned. lol) they can disrupt my sleep as well.
The internet did. Reading a certain comic(A Very Sonichu Adventure) and making Sonic Rugrats. I stood up longer than I thought. I made a DeviantArt JUST to read this comic.
But the connection went BSOD and I fell asleep for a couple hours.
