A question about chakras and auras

I would like to ask if this is possible: I have been noticing that when someone is in a certain mood, there are colours on a different level to the physical within their head. There are combinations like purples and greens for when someone is thinking and when they are very happy there are shots of white. They are like little particles which glimmer. These are like auras but inside the head, or like chakras. When I see someone I can instantly know their colour. People close to me I have noticed, will change colour depending on how they are feeling. When negative thoughts invade there are shots of black in their head. This is like coloured energy within their minds.
Reading all that, would you think this is something that is possible?
I am reluctant to add this, but I have a mental illness and people who I've told are saying this is a delusion but I believe that I have some sort of gift. Please judge me based on what might be able to happen rather than my mental illness.
Thank you.

Zeal, your perfectly capable of 'sensing ' the emotional states of people. Perfectly able to let your intuition 'see' them in whatever 'code' works for you. There is nothing to worry about or doubt in that.
Always be open to the fact your 'sense' MAY be wrong though; at least in some cases.

Chakra isn't a physical manifestation. I would know, I teach meditation. Chakra represents different things to different people, sometimes to describe emotions, but they cannot be seen, because chakra is just a concept that doesn't truly exist, like the concept of good and evil.

By the way, when you are an infant there are arteries in your eyes that later die and just stay there, sometimes you can see shadows of them, and if you close your eyes and face the sun you can see flashes of colors because of them,. That might be what you are seeing.
