The inverse pentagram has many meanings- one of which is bringing spirit into matter. What do you will into your life? What do you want? What are you trying to manifest into your life?
A reversed pentagram, with two points projecting upwards, is a symbol of malevolence and is a symbol of summoning dark forces, perhaps your vision is of a ritual for a baneful casting. It reminds me of the lucifarian principal of order out of chaos as it overturns the proper order of things. It is a symbol of the pagan goat attacking the heavens with its horns.
