Because you're still pure and innocent of age, I believe that you're not quite ready to have any type of communication with this ghost, unless any of your close family member allows you to, or have a wide understanding of the paranormal. Communicating with any spirit can be really dangerous and can drain alot of your energy, which is why you have to know how to protect yourself FIRST before taking any further action with this. This is why is best to know that one of your family member understand these things so they help you with this type of process. Another reason why you might communicate with this is because sometimes the ghost does have a message for you. Of course, you should realize that most ghosts were previously living people. Therefore, ghosts reflect human personalities. If a ghost was friendly and warm when he was alive, he will probably be likewise in death. However, if someone was reclusive and angry during life—it is very likely that his spirit (ghost) will reflect these same qualities. For the most part it would be best to just keep it as simple as possible, first off Never FEAR! People who are exceedingly fearful/paranoid/angry tend to attract other like-minded spirits. So, don’t dwell on negative thoughts! Say a short prayer or affirmation if it makes you feel comfortable. Secondly dont pay to much mind to the ghost being, it has been my experience that we attract what we focus on. So, if we are excessively fearful, and dwelling on “evil spirits,” then this is what we tend to attract. So its better to think of nothing when it comes in your mind, dont judge just remain calm. And last protect yourself, you can use a prayer such as "May all that is not in accordance with the highest will of God, within and without my entire being, be immediately transformed into divine light." If you decide to use a prayer, it's important that the prayer/affirmation has meaning to you and that you feel comfortable using it. Or you can also use protection supplies such as hanging garlic or a horse shoe on top of your door, or place mirrors near the door entrance (ghost gets scare when they see their image), and/or you can envision a white light surrounding you from head to toe. The white light is protection against danger and harm.
As long as you are mentally and emotionally stable, the chance of encountering negative spirits is very, very small.
Empower your mind and think positive thoughts. People who constantly think negative thoughts or live in a constant state of fear make it easier for bad spirits to control them. Ghosts are more likely to avoid confident people who emit positive energy. Hope this help a bit, Im only telling you from my very own experience it maybe best to simply live the ghost alone and move one with your life, you probably attracted him in some way, especially because the similarity on behalf of the age.
