About destiny and our ghosts...

Sometimes I ask myself: "What happens if people are living in dreams and destiny alone is the end of it?"*
I believe, the only solution for this problem was found in ghosts. However, "What are ghosts?" I would not like to discuss spirits or supernatural topics; as I do not believe they exist. Ghosts are our fears, dreams, beliefs, problems, joys, wishes and sadness. Between destiny and a person’s ghost, is their life. A dream that revolves around people, sites, countries, places, moments, and an infinite amount of things that we face and overcome in life; I will discuss an example.

When one is alone in a new city and all of their memories return in a ghostly fashion; the person remembers who they are, what their history is** and the people they love.
Today I stayed behind in class for speck (?) in English and in the group I was in, the group leader asked me about my country; they asked about my hobbies and the people in my country. However, I couldn’t cry, because I remembered that I was all that my story was; I was a person who had a destiny and I had to keep it, because now, as time passes by, the dream will eventually be over. I believe one will take only what they have done in their reality, with them.

*I'm not sure what 'it' is, maybe be more specific? Do you mean 'it' as in life? 
If you want to use 'it' you must first state what you are speaking about. If you said:

'I sometimes think about life - I wonder if destiny determines the end of it.' - This would make more sense to the listener/reader

**I'm not sure if you were making a different point with 'history and past' but you can be a bit more specific such as 'their country's history and their past' or 'the life they have lived and the history of their country' etc. This was only confusing because 'past' and 'history' can be naturally used interchangeably. So it's hard to distinguish what the speaker means exactly.

Hope this was helpful :)
