Dream of child, grandfather

Hi Members, I am new to this forum and had a dream that has been continuously in my mind. Please forum members help me understand this. It is one dream with two scenarios in it! Scenario One: I am in a house (Not known to me), where I see my grandfather (Deceased long time ago) with an un-known child (about 10-14 Years old). In my dream the child is alive but my grandfather is a spirit watching over this child and is seen with him. I also think the child cannot see me or my grandfather. I speak to my grandfather and in reply he just passes a mild smile (No Answer). The environment of my dream felt quite normal. My question is: What does this child represents in my dream or what is their relationship? I have never seen my grandfather, so what could be the possible reason of this dream? Scenario 2: In the second part of the dream, I saw myself pulling a long hair (Black in Color) from my throat. I wanted to get rid of it but at the same time, I was very careful pulling the hair, as I wanted to get it all out without breaking (I am quite sure, I was able to pull the entire hair). Thanks in advance for your valuable suggestions. Thanks
