So basically I've been seeing ghost and shadow people since I was real young. (Probably about 5 or 6) As I've gotten older I've become pretty used to it that it rarely bugs me much anymore. I normally see people standing behind me. Or feel as though something is behind me. Like when I was in high school I used to look behind me and catch a glipse of a little boy.
When entering someone's house I might see something in a conjoining room that they don't see. Once I was in a friend's house and it was just him and I and I heard what sounded like two older men chatting probably not 10 feet away from us.
But like I said the only two people in his house were him and I and the only other two people who live there are his mom and brother.

I guess basically I would just like advice on how to work on using this skill. And maybe some advice on how to stop being so frightened of it sometimes. I really do appreciate the fact that I can see these things but I'd like to put it to better use than just noticing something.  

Telling 'stuck' spirit to turn completely around and see the white light and to move into it is an important step.  If they were talking and getting your attention, you are the one that can discourage them from remaining around this place.

Thanks for responding.

They don't normally talk to me.
Sometimes I'll get them in my sleep talking to me.
But rarely when I'm awake.
Usually I just see them pretty far away from me, watching me.

no no no you were just na part of a astal diagolouge and that is what has got you stuck enough to get you sarted on your journey of spirituallity. look for the signs and colour that stand out to you and look into them. !chakras!

Take charge!  It is your own consciousness.  Welcome who you want and dismiss others is how it works.  Send all spirit entities to the light.  In that way, those that may be willing or able to work with you will return from the light.
