I drew you a picture and I don't remember making it

So I'm tired.

Not 'oh I should probably go to bed' tired, like 'HOLY MOTHER OF FRENCH FRIES I'M GOING TO PASS OUT ON THE FLOOR'

So what did I do upon realizing how tired I am?

I drew a god damn picture. I don't even know what the hell this is. I don't even remember drawing it, I passed out for a while after making it.

Can somebody explain what this means? Because apparently I draw cartoony monster shit when I'm tired. 

And zombies. I draw zombies. 

I can't explain this. 

I'm gonna go to bed, and hopefully wake up slightly less psychotic in that I don't feel like drawing horror movie nightmare fuel.
