Voices On The Train

This story will be a very quick experience that happened to me while taking the train to my dad's house. I am not sure if this is something paranormal or not, but I want to post it to see if anyone on here has any ideas.

As I said, I was travelling on the train to my dad's house near the city. The ride can take about 45 minutes and is usually busy as we catch it during peak hour when people are coming home from work. I was on the train with my dad and my three other siblings.

I remember that train was particularly noisy though it was so long ago I can't remember whether it was because I had headphones in and listening to music or if because it was so busy there was lots of talking. However there was lots of noise.

While on the train I heard a voice in my ear. I don't know what they said but it sounded like a man. His voice sounded like it was coming over a speaker, but I was too far away to understand what he said, like the words were muffled. I asked my family if they had heard anything but they said no. I told myself that it was maybe a speaker on the train or something but it sounded like it was right in my ear or in my mind even. It has been many years and I still remember this in my mind very clearly. I even vaguely remember the voice I heard.

Thinking back on this experience I wonder what it could of been. If it was paranormal or spiritual, like maybe a ghost or an angel even? In my own personal beliefs I believe in angels and at church we were taught that everyone has an angel waiting on earth for them, but at the time I wasn't baptised and so therefore in my belief wouldn't of had an angel 'assigned' to me yet. I don't really know but this whole experience confuses me more than any other I have had before.
