I just standing and I experienced a heat go throughout my body, my hearing became dulled as if someone was speaking to me miles away, I became dizzy with tunnel vision to the point of passing out, and after that subsided within five to ten minutes my arms began to tingle severely. My friend was present at the time. She said I turned my head as if like a dog to hear her and then my eyes glassed over. Little freaked out about what this could mean. Any suggestions.
