Hey @SerenFox, sorry to hear you’re having issues with your neighbour 
What do you think this means? I think that’s the opinion that really matters.

I have no knowledge of candle flame magick, here’s a link to Francisco’s post 🕯️ Flickering Magic: How to Read Candle Flames, Meanings and Interpretations
You can always use your preferred divination method to find out who it is, if you want to; some do, some prefer to take solace just knowing someone is there.
And congratulations on a successful spell… don’t forget to celebrate the little victories, because we don’t ever seem to ignore the stumbles!
