Dream of mad, father

There is a father and a son. it was a boy but i felt it was me. They were playing happily,then suddenly the father disappeared and i fell from a strange place. the place was like my school in college and was like a carnival too but there were classrooms. I was so sad and decided to go to that classroom and i have seen my classmates i college but then didn't see me even though i was walking noisily, i called one of my classmate but didn't even bother to notice me, i was shouting but it seems that he didn't hear. I was mad and managed to get to that classroom and while i was walking i saw Ferris wheel, people playing bingo. I continued walking and suddenly i saw some of my seniors in high school they were singing a song which i can't remember. They were holding each others waist and happily walking around me, i look at them and smiled, they dressed in jumpers, all of them and they decided to bid goodbye, i was sad again.
