Hi Winter Rain

Firstly, am impressed with your dream interpretations from what I have seen

As for this dream, it seems that it is quite a primitive setting, as in the cave and shaman.  I think that may be a clue.

Also the repeated dark symbology - the cave, the people, to me this points to something that you are not consciously aware of, but perhaps something that you are seeking - the truth.  The truth about who you are?

The hot coals in the centre could be something burning inside you possibly?  At your centre (centre of the cave)?

You have a shoe with a number 5 on it.  The shoe you are walking in / life path makes sense here.  To me the glass jar with the burning candle could be representative of the passing of time.  The number 2 residue... I am not so sure the significance of the number 2 here really, looking into the glass jar could be looking into your soul, perhaps this is what you are doing in a spiritual sense?  Looking into yourself to find answers about who you are?  Perhaps you have been given an answer (the number 2) but you don't fully understand it yet.  Perhaps the burning candle - passage of time - will reveal this.

Not really an answer but hopefully it helps.

Sweet dreams,
Rook
