I'm new here , Just got my account activated!

I believe in Wicca , I live by Wicca.
I did something 15 years ago (give or take).
I'm 28 years old , What I did 15 years ago still haunts me , I can't stop thinking about it.
I was young kid , about 13 years old. Curious of the unknown , a true weirdo.
Didn't realise what I was doing back than - I took two empty cups (simple coffee cups) and put them on two sides of a wood board ( like a small 2 by 4 board ) , so 1 cup on it's left edge and 1 cup on it's right edge.
I took paper (blank , without anything written on it) and tear it apart piece by piece and threw inside each cup.
While I was doing it , I remember saying some things like "i summon you bla bla bla" (probably saw it in a movie, I had a wild imagination)
Afterwards I took matches and light 'em up , threw 1 burning match in each cup.
and than it happen , I will never forget it.
from the left cup , rise 2 feet of flaming tower.
2 feet of flames that came from my small coffee cup which was filled with few pieces of paper and burned with a match. I will never forget it.
I screamed and cried for my father to come but he was taking a shower so I ran to the kitchen took bottle of water and when I came back to my room there was no more flames , just burning pieces of paper inside a coffee cup.
It really haunts me till this day , I can't stop thinking about it, If anyone have ANY idea what it could be , I'm begging you - PLEASE contact me and share me with whatever you know.
Thank you for your time , Hope you guys having a great day!
