I experienced bands of electric blue and gold rings 1/4" apart moving seperateley up each leg merging at trunk continuing up and over each arm seperateley equimulating approximately at shoulders and continuously starting over with sounds of gongs at different tones some double in pitch resonating through head, lasted aprox. 5-10 min. Very calm and relaxing, no fear felt. I do not know the meaning, this has happened before but never as intense. Any suggestions of meaning?
