Young And Confused

Let me start by saying that I'm a 14 year old male. Ever since I was a child I can remember the "voices" as I called them. They didn't happen often but at least 1 or two times per week. I could her people call out my name and sometimes even now still do. When I was about 4 or 5 years old I dreaded going to sleep as I knew the man would be there. Around this time I was young and didn't want to sleep by myself, so I went with my mother. The same thing would happen every night. The door would already be open and a figure would walk in slowly and moved like a shadow and in fact, looked like a shadow. It would go up to my mother and then me when I would close my eyes so tight and pretty much pass out in fear. Now I ALWAYS have the door closed when I sleep. It has to be all the way or I won't get a good nights rest. My last little bit of my life are my issues. Whenever I'm in a very crowded place like a mall say I get a bad feeling or anxiety. Not all the times but sometimes and it feels like I need to get out. From what I understand these are signs of being a medium. I really think that I am closer to the spiritual world but I'm not sure if I'm a medium or not. Can someone please help me. I want to know the truth about myself and if I'm too young or not. I also understand id need training. Where is training available and when can I go since I'm busy with school. There's also the fact that I'm a catholic. I feel that God makes everything a way for a reason and I have also heard of some mediums who say they still are catholic. Can someone please help me? Also, thank you for taking the time to reading this.
