Let me sleep!!

Was trying to go to bed early just now!
Went to bed around 10+ pm and I fell asleep.
Around 11 something, I felt someone came in my room.
And it was my parents -.-
Went back to sleep.
Around 12 something, heard my parents go to bed.
Went back to sleep.
Around 1 something, woke up for no freaking reason.
And so I'm sitting right here in front of my laptop typing a blog.
Is because I couldn't go back to sleep.
Tried to go back to sleep but couldn't.
Why? I have no idea.
Anyway going back to bed to roll around.
Peace
