Can The Soul Travel Outside A Living Person's Body?

I'm relatively new to this site, please check out another article that I've written before this about my ability to predict the future and stuff. This happened 2 years ago. My parents are from India but I've been born and bought up in the United States. Our relatives live there and we haven't visited them since a long time, a really long time I'd say! My dad had an elder sister, she used to live there since the past 12 years or so. She has 2 sons and a husband who she left behind. The story's about her- I hadn't met her since 2001 that's the last time I'd met her and my cousins. My parents had been to India in 2007 when her older son got married but I couldn't go due to my tests at school. She wanted to meet me really badly. We'd just skype or email each other and stuff or talk over the phone.

She was suffering from cancer and I'd spoken to her before she made her last trip to the hospital. She said that the doctors said there were clots in her brain and she need to be admitted. She didn't want to go though, she wanted to be at home. They took her nonetheless. Within 24 hours her condition worsened and she was in a state of coma. My dad had only her from his immediate family as my grand parents have passed away too. This is the incident I'm going to talk about--

She was in a state of coma, I just came back from school I was in the driveway parking my car. I rolled up the windows and my mp3 player was also off, plus it wasn't a windy day or anything. There wasn't anyone outside either. I put my hand on the backseat to grab my school bag and there I hear my aunt's (who's in India in a state of coma) voice. She just said my name. It wasn't loud, neither was it a whisper. I got so freaked out! Even as I write this I remember that day and the hair on the back of my neck stands up. She hadn't passed away then, she was in a state of coma. Do souls travel? I mean she was in India and we, in the United States!

She passed away within 19 hours, they gave her morphine to ease her pain and slowly took off the ventilator with the consent of the family.
