Dreaming during class

Date: 9/22/2020

I fell asleep during online class and the teacher was talking about black segregation and it went into my dream and I legit saw it like a movie, I both saw and heard how colored people weren't allowed to buy property but were only allowed to rent and how whites didn't want to rent to colored people because they thought it would lower the houses price. And how the reason for segregation is because of how colored people werent able to save up money to pass on and they were essentially stuck. And I saw it all in my dream
