Hey everyone.
I cast my first spell today. I've been interested in witchcraft and wicca for some time now. However, I decided to do plenty of research and become more aware of it all before I cast any spells. And now I think I am pretty informed about most things.
However, the spell I did was a love spell. And after proceeding with the spell, my candles flame got slightly out of control. And by that I mean the flame grew unbelievably big at one point and then it seemed it was almost like being blown.
It eventually went back to normal but I heard a sort of 'popping' sound and saw my glass had cracked. This also happened a few minutes later again.
Could anyone tell me what signs these could be? I'm not too sure.
Thank you very much!
