Blue Spirt

I have been seeing spirits all my life from the age of 5,and hearing them speak to me and to give me advice but a couple of days ago I saw a blue spirit of a man it was a full apparition he had a blue suit on and just don't know what it signifies or means so if anyone can help me to understand the meaning of blue I did think that it meant healing but I am not too sure. As I have said I have been seeing spirit from the age of 5 always In full apparition they just appear everywhere that I go especially at all the homes I have lived in and they always tell me what is going to happen in my life, such as when I was in danger. One day I was walking home with some friends through a park we were going around the park the short way when all of a sudden I heard my grandmas voice telling me to stop and don't go home that way as there was a man hiding behind a wall waiting for us so immediately I told my friends who laughed but we waited and yes we did see a man who was waiting for us as he popped his head out and we saw him, so spirit saved my life. They have saved my life quite a few times as well. When I hear them its normally just really quickly like my mother calling my name or one of my loved ones and sometimes they do give me visions just very quick ones but its nice to know that they are all taking care of everyone of us as well and that we always have someone guiding us through our life's and when we need help they are always there. When I am low I see my spirit cat as well that is comforting.
