Does this happen to you guys too?
Yesterday I was coding auth for node.js with help of tutorial (I'm pretty new to node.js). I was pretty sure that I understood how it works and I turned off my computer. Then when I was in bed ready to go to sleep I tried to go through the code in my head, but I completely forgot everything I wrote. I guess I was just copying the code without even noticing I didn't know how it works. Now I'm trying to learn it once more.
