I have a weird dream

This is gonna be a long story
The dream started in the classroom, it was breaking time .. me and a boy were talking ( i dunno who was him) then suddenly a guy around 22 years old , smoking a cigarette and tall came n yelled at me , i came to him then he brought me to somewhere and kissed me , not so long , suddenly that guy been killed by a throwing-knife , it's stabbed his heart, i ran away and got out from that school ,i saw a city but around that school was so dark , far away , there's so many lights sparkling (like a big city) i started to follow someone using a motorcycle ( i forgot where did i got that ) .. he lead me to somewhere even darker (like a dead village) then i turned away and followed the lights, i arrived at a beach , there's a house nearby , i wanted to knock the door but suddenly the family got out .. it was four of them (husband, wife , daughter n son ) .. i followed them n walked around the beach , i arrived a lil grave then suddenly i heard something , a woman voice , she said "this is the grave of the ocean's princess .. after i heard it , everytime i was humming , the ocean wave would be flat n peace .. but if i stopped , it would growing big and there's storm ..then.. i woke up

What you think ? is there's something hidden from it or ?
P.S. I can remember my dream completely sometimes
