In my dream, I saw that my mom would spank me when I wouldn't wake up when she asked!

(It ACTUALLY HAPPENED! Oh my god)

believe in your sub conscious mind, this is an example for it.

your mind probably caught it while you're sleeping. maybe you can hear even while sleeping!

I saw my friend died because of corona and when I woke up mother of my friend called my mother to tell that he is died because of corona

Well, that's somehow relatable with me. When I do something, I just realize after a few seconds that, Oh! I just did this and why am I doing this again? Like, when I do my lunch, (dinner/breakfast whatever) I feel like I did this today, at the same time, same food everything same but I think that I already did it. Sometimes, when I sleep, I feel like, I was just sleeping before a few seconds and I'm doing it again. Before doing something, I feel that I already did this.

When there was the time where we wrote exams and waited for them to be back with the grade, I was really stressed because in German and French I didn't so very well, I thought, and I dreamed that I got both back and both had very bad grades. But when I got them actually back, I had good grades. :]

I think you may have heard your mother talking and it entered your dream. Once, when my mom was asleep, I asked her what I should make for breakfast. Before she woke up, she saw me asking that in her dream.
