I was in front of my house, and I went inside, and there's a girl she's beautiful, and she start to yelling at me, she said "where have you been? I already cooked a delicious dinner for you let's eat!" I was like "wait! Who are you? This is my house" she's went furious and yelling that "who am I?? Are you fucking serious?!! I am your wife, don't act like a fool and make me angry for now." what? My wife? And I asked "when we got married because I can't seem to remember that" . And she yell again even more furiously" she throwrd her clothes down and with only a sexy lingerie left on her body she said OK You know what? You have done it, no sex for tonight!" I was like what??? And she went upstairs. And I was sent to another world where I was back to when I was in high school, I'm inside my class I sat beside a girl I think It was my ex back then but her face kinda blury, I was in the middle of a math subject, I saw my note and the textbook and I was like, whatt??! This is not high-school math subject, this math problem is so advance I can't even get a grasp of it, but all of My classmate seems like they got no problem with it, and the teacher is not my math teacher back in high school but he is a biology teacher, why he teaching math?! He came to me and saw that I don't even write anything on my note and he started to yelling at me and I asked I want to go to toilet for a minute. And so I went. Inside the toilet my friend come along and said what's wrong with you bro? And I said I don't know. Then I woke up.
