I had deja vu and i knew it was from my dream

in eight grade i had a dream i wrote a note in math to the boy i liked. in the dream i was with two of my friends but we werent in the same class together irl and i didnt sit wear i was supposed to be sitting. in this school i had a class call win where we went to one of the core classes in your designated homerooms hallway. i had math win and this was around the second time i had math win. i had a crush on this boy and i was talking to my friend about it. we can call her A. A and i were talking about my crush (P) and i told her i wanted to write a note to him but i was scared. then, i had a memory but i didnt know of what. the set up was the same as in my dream and when my friend started writing a note, it was on the same part of the paper the dreams paper was on, the top. i told her i had a dream about this and she was always a believer in dreams coming true so she encouraged it. my other friend was there and i had her give the note to my crush. that was the end of both the experience and the dream. it was strange but since then most of my dreams have come true. im scared though because i had a dream my dad khs
