Ability To See Spirits

I posted a story about how I wasn't sure if I was seeing spirits or if I was just making myself do it. Now, I know for sure.

I need some advice though. Whenever I see a ghost, I only see it for a split second, and it is almost like I know everything. I can feel its emotions and know what its problem is. Is this possible?

Another thing is, The first time a spirit talked to me -while awake- was just the other day. I could see them before that but never did I hear them. The funny thing is, I didn't hear her physically, it's like I heard her speaking inside of my head. Is this normal? Possible?

I am really confused about all this. My mother's psychic friend told me that she felt like I had the ability to see spirits, but this was before I could actually physically see them. I first started off with dreaming about a spirit, and this is why I was talking to the psychic. Because of a confusing dream about a ghost. She then told me that she thought I would be able to physically see spirits and a few months later, I figured out she was right.

The major thing that gets me is, how long they stay -only a few seconds literally, and how I hear them inside my head, not physically. I just need to know if anyone else has these same experiences.

I am always feeling that a spirit needs me to help it, but the only problem is that I do not know how. Another thing is that I fear that where I really do not know much about this, that I may do something wrong. I have also heard that you have to be very strong to help these spirits. I just feel like right now I am so insecure about my ability, that I couldn't do it. But, I feel awful though also, because I feel like God chose me to help these spirits. I am only 14 this is all very overwhelming for me. Any help would be greatly appreciated.
