Mysterious Candle-light Appearance and Ghost Ecto Ball

This video recording has recorded a mysterious Candle-light like appearance that is invisible to the naked eye. This mysterious phenomenon appearance was captured while I was video recording the surroundings of the Old Chinese Cemetery using combined internal and external infrared light (IR).

However, this mysterious phenomenon was captured at about 10 meters away and was only visible at this distance, because when I came nearer, the light disappeared. Further analysis on the video recording shows that the mysterious phenomenon had changed in appearance in three stages which are; First, it appeared to be likened to a candle-light. Secondly, it became more prominent and another mini light appeared at the lower part, and finally  expanded and at the lower part appeared another bright light.

From the analysis, I believe that this phenomenon most probably is generated by spirit energy, unlike the night environment that might glow as a result of natural phenomenon such as certain mushrooms and decaying wood which glow in the dark in tropical jungles. Furthermore, the glow that comes from a certain mushrooms and decaying wood only become more prominent in the darkness and would disappear when touched by  IR shining on it,  because the glow is not powerful enough to be noticed under IR.
