The symbol is a circle. It has two lines on top of it that are straight but curve up at the ends. Inside is a bunch of other lines. I can't really describe the symbol, but I keep dreaming about it and it's always on my hands with fire. Can you help me?
Also I just turned 19 on December 20th and that's when the dreams started. Also I sometimes have dreams that come true. I don't know if that helps. Lol.
I have no idea what that symbol could be. I would suggest you buy Signs, Symbols & Omens: An Illustrated Guide to Magical & Spiritual Symbolism by Raymond Buckland. It has a number of different symbols in it that might connect with you. Fire is a sign of passion, desire, and drive. It is through the element of fire that we connect with the spark of the divine which lives in each of us.
It's not uncommon for one hand to feel heated or hot and the other hand to feel cool or cold.
I'm sorry I couldn't be of more help.
