Is it normal to forget things from the previous day often? - eviltoast

Due to a situation I find myself in, my daily habits have changed to a more simple daily schedule.

However, recently, I’ve been noticing that I struggle to recall certain events that happened the previous day:

What I ate for breakfast, what I did at work, what I learned in my classes, etc.

I don’t know how long this has been happening. Am I just overthinking it?
