Smoke and flame questions

So in the booklet I see Lala says active flames means the presence of spirit is there and they’re listening but my candles I lit healing as well as ahari are both dancing wildly with tall flames and there was quite a bit of black smoke coming from healing at first and just white from ahari but then healing started to go from black smoke puffs every now and then to some black and some white then a lot of white then occasional black and now it’s going back and forth between a mix of both white both candles having high flames and crackling sounds could anyone tell me what a mix of the smoke means? I checked on it later and there’s no smoke now but just tall loud flame
