My Own Psychic Experiences

I have always had a feeling that I was psychic, or a medium. I am not completely sure yet. I can not see the dead like the boy from the sixth sense. I can at times see them in my mind and communicate with them telepathically. Although it is difficult for me because I can't trust myself. I mean I do some of the time but anyways back to the story. When I was a child I could sense things. I could sense when something bad was going to happen, or sense what others felt. I am not an empath. I don't feel others emotions all the time, it only happens when I am supposed to help them. Once I saw this shadow right in front of me. That is one of the only times I remember seeing a spirit outside my mind. The second was when I was in my room and I saw someone walk by. The most recent time was when I saw this lady wearing a blue robe or hooded something. Not sure, when I noticed here she disappeared. I think because the scare me at times I block them out so my ability is not as strong as it could be. I want that to change. Anyways I have been told that my energy is strong... Not sure what that means yet. Okay so I realized I could talk to spirits when I bought a book titled so you want to be a medium. I quickly started communicating with my guide cole. Now I want to say this, I can not hear them. I feel the message, and the communicate clairvoyantly. Okay so when I got older I noticed that hey others can't feel when something is going to happen. I discovered Wicca and mediumship sometime later and that has furthered me in my abilities. I may have even talked to an unborn child once. Um some guy was having a ruff time over the lost of his child and all of a sudden I had this feeling of what I should say and as though I had no choice I had to say it. And I was right, I knew exactly what was wrong without him having to say it. Okay I have a question for you guys, I have this feeling that something big is going to go down soon. And that something is going on in the spirit world. What do you guys think. I have 2 or 3 friends who are like me and they feel something to. Oh and one last thing, do the numbers 11, 5, 477, or 20 mean anything to you guys?
