I can and people have said they see mine.
I’ve always seen it and usually 99% of the time I can feel a vibration in them. It sounds crazy - hard to describe but it’s like when you run your hand lightly over something that’s plugged in by not turned on. You feel the humming. But the auras, I’ve only seen red, orange, yellow colors which to me represent happy people. I cannot view evil.
Most people I see don’t have auras.
