I see dead people, and i want to know why.?

its been happening my entire life. i see dark figures. or ghost that seem like real people. they talk to themselves or each other in whispers. i also see auras, feel energies from different people, and get extreme anxiety. not only in my home but in the homes of my friends and family. i also hear voices that i cannot see. i control it by ignoring it. but the auras i bring on myself. they have only touched me once on the face. what do you think i have or am??
