I Can Sense Auras

I've always heard about people being able to read auras based off of colour but never being able to 'sense' them.

When a person walks into a room I can sense their presence, even if I don't get anything (I'm listening to music) or see anything, I can sense they're there.

I don't feel on edge about anything so I don't believe it has to do with anxiety.

I find that if I'm in a room with a lot of people there are certain ones I can pick out more then others, but unlike most it isn't a person who emits light in their presence (I've been told by many I do) I tend to feel something dark.

I'm not sure what the dark is, I've always thought it was sorrow, anger, maybe a dark person but I feel like I want to find out what it is. Maybe I want to help them?

I've heard of empaths but sometimes I'm not intrested in hearing my friends vent because I have a lot going on myself.

However when I see an animal in need I will not hesitate to help them.

I've talked to numerous people about being able to sense something about a person and they said ist a gift, my mom trusts my gut instinct more then she trusts hers in most cases. If I say I got a gut feeling about someone she'll believe me right away.

My gut feeling also tends to be right about people who will do something bad to me or someone else, such as harassment.

I was wondering if you can sense auras without seeing them, or if I'm just reading emotions off of people?

I however cannot read emotions off of people I'm close to, I'm not sure why though.
