Losing track of time

I do this often. If I take a nap when the sun goes down I wake up thinking it's the next day. Scary shit. I have to then check the date on my computer to see what day it is. True story. After the first 10 minutes of waking up I have to remember what I did that day. It's freaky as fuck. It's like I'm in Back to the Future, but it's not as cool. I am Baliwala. I need to buy a watch. That is all.
