I Am Getting More Afraid With Psychology Class

My psychology class is getting scarier within each and every class. It's not haunted or something, but the lessons in class is giving me the creeps

Today, I learn about memory. To make it simple, our brain goes through several processes before an information can be stored in the long term memory (LTM). It goes through the short term memory first, and through some other process which I can't remember right now.

Then, my lecturer shows a video of a person that cannot process the memory into the LTM (his brain is damaged). The person in the video cannot even remember what he was doing yesterday. Every time his wife came into the room, to him, it is the first time. He even wrote a diary every minute, but when he look at his diary again, he says that he did it unconsciously. Somehow I can feel the same thing happening to me. I can't imagine if the same thing happen to me. I will not remember my friends, I can't even remember what I did yesterday...

Thanks to Allah that I am still fine and healthy by the time I write this post. It makes me become more thankful to Him for everything that He gives to me.

Some questions raised in my mind:

- Why do Allah creates a complicated process for our brain to store informations?

- Why do we have a short term memory and long term memory?

- How can the person with damaged brain continue his life?

Whatever the answer is, I believe that Allah knows better than I am
