So recently my mother asked me to come to a house with her because she feels an evil presence. This house is FULL of dolls... While listening to music in the car I calmed my mind and asked the divine spirits to help me. Shortly after while still meditating, a depiction of me standing in front of a large bright pentagram flashed and the pentagram shined bright light on me making my entire body look white and I suddenly felt a wave of goose bumps all over my body when the light hit me. Can someone tell me what this is and if I should be concerned?
Well... Actually, the light pentagram didn't came from you, but from the spirit itself. I think you should be considered. I've been told that light symbols next to spirits indicates signs of possession. By my opinion ask from the members here to tell you any cleansing techniques.
A house full of dolls? Now that is just creepy. Personally: I see great adventure in there! Going to houses to look for "collectors items" or items that were made in the early days is something I have a huge interest on. Though I will do some inquiry regarding the previous owner and the history of the dolls if I were you. One of the dolls could be the same age as my grandmother who is already one-third older than my age now and possessed. If there was, best indeed to know how to cleanse the house. Check for any paranormal activities.
I wouldn't be alarmed at all. You prayed for protection and your prayer was answered by higher beings.
Pentagrams or pentacles work as a symbol of protection, some people use it to symbolize the elements.
