Thanks, guys.
Normally, I’m a night person, too. I’m gonna go to bed soon now.
I figured it was something like that, but it just felt so freaking WEIRD.
You’re still up?
Go to bed! 
I am glad you are felling better today!
And I second what Astroboy14 said.
to me when i am falling asleep reading, the problem is i do not notice that moment when it has stopped making sense and i am just wasting my time. after i come back out from it i have to ask myself where did it really start to happen ? i usually have to wind back about 2 paragraphs before i begin to recognize the text as something i have read 
I used to not be allowed to fall asleep with my contacts on- my mom would get quite angry if I did. But the urge to drift off to sleep in front of the television was too great.
Somehow I learned to laugh and react to the television while sleeping.
It was always a shock to me to “wake up” some hours later and realize that I had actually been asleep.
