Protective Symbol Dream

I had a dream where a dark entity was after me. I was running away from it and I found a candle with a symbol on it. The candle was very difficult to light I tried multiple times as the entity got closer and closer. Finally I was so frustrated and scared I yelled "light" and whoosh it lit up. I later tried to recreate the symbol on the computer. I have included what I came up with below. Anyone have any thoughts on this? Has anyone had a similar dream?
