Well, you can definitely see auras since you are quite often! It's a gift. I explain what the colors mean in the article you asked this question from. So you have some clairvoyant ability, and it could get stronger if you meditate. Green is usually a healing color, so if you saw it while having cramps, maybe that's what your body needed at the time to heal what was bothering you physically. Red is usually associated with strife or anger, so a bad headache could cause you to see red. Do you know the expression "seeing red" normally used when people are angry? That's where it came from. Blue is a calming color. Does your husband normally have trouble of some sort with his legs? The blue would mean it was getting calmer or not as bothersome. Lavender or violet is the highest vibration, so as soulmates or two people in love talking about serious issues, this is the most spiritual color. Did you see it around his head? It's really great you can see all this. Edgar Cayce has a great book out on auras and color interpretations, you can find it on Amazon and it can explain auras to you better than I can here, or in the article, I wrote you can pick up a few pointers.
