Response:

All of these experiences are fine and normal and represent the natural process of release that happens in the mind and body as awareness begins to expand and open up. 

These experiences, seeing a flame on the forehead, feeling light/dizzy in the body, and seeing colors, are not important in their particular details which relate to your individual history, but they are important for indicating that the meditation is working to transform your awareness toward a truer awareness of your real self.

Love,
